Learn more at swimmingpoollearning.com. I'll start with this one. Is it normal for your chlorine
1:44
to disappear overnight? And the answer to this is yes, some cases, it is very normal for your
1:51
chlorine level to disappear in one day or 24-hour period. And this can be due to a number of factors
1:58
and I'll list a few here that are the most common. The first factor, of course, and this is one
2:05
that Bob Lowry talks about, and that is the 7.5% of free chlorine to sinareg acid and just to keep
2:13
it simple, if your sinareg acid is at 100 parts per million, that pool needs 7.5 parts per million
2:19
of free chlorine so that it's just going to be able to protect it from, of course, being destroyed by
2:26
microalgae, anything in the water. So there are times when your pool maybe at 3 parts per million,
2:33
the sinareg acid might be at 120 parts per million, and that 3 parts per million of chlorine
2:39
is used up in that 24-hour period very rapidly, fighting the microalgae and the pool.
2:45
Now this is algae that you can't see yet, has informed completely, you don't see the yellow
2:50
streaks on the wall. I remember one of my members, he had someone doing some work over it,
2:56
one of his accounts, another pool company, and they said, yeah, yeah, he's not doing a good job
3:00
because I see all the invisible algae there, there's a lot of algae in there, it's clear algae.
3:05
He was trying to explain, I think, microalgae to the customer, which you couldn't see
3:10
anyway, as a pool service provider, it's just his way of trying to get the account,
3:15
because in all intents and purposes, the pool was perfectly blue, and there was no
3:20
clear algae in the pool at that point, but microalgae can form, and you can't see it,
3:27
and this will consume the chlorine very rapidly. You could also have a high phosphate level in the pool,
3:32
this is something that you can't test for with your standard Taylor test kit,
3:37
it's something that will also destroy the chlorine level really rapidly in the pool,
3:42
and that's why it's important to have phosphate test strips with you, you can see with the
3:46
phosphate level, anything over 300 parts per billion should be treated, because that will destroy
3:52
the chlorine level pretty rapidly in the pool if you have high phosphates in the pool. It could
3:57
also just be a low chlorine level, two or three parts per million, and it should be at five or
4:02
six depending on that 7.5% formula, and you're having a really high UV index day. If you're
4:08
in Texas, you know, I'm talking about with UV indexes, it's pretty extreme, and Bob Larry says that
4:14
a pool will lose about one part per million of free chlorine per day, just by the natural
4:19
effect of different things on it in the environment, but if you have a really high UV, UV day,
4:24
and the chlorine level is low at three parts per million, there's a good possibility that the
4:29
sinaric acid, no matter what level you have of that, is not going to be strong enough to protect it
4:34
during that period, and that three parts per million will go down to zero within a 24 hour
4:39
period or overnight as the question was posed earlier. So it's one of those things where these are
4:46
the most common factors where the chlorine level will be used up, stuff that you can't really see
4:52
in the pool, stuff you can't really see in the environment like the UV rays hitting the water,
4:57
and it's something to be aware of. There are like outliers like iron in the pool water or nitrates,
5:03
but mainly it's these factors that are pretty normal in the summertime that cause the chlorine
5:10
level to zero out within 24 hours. Here's another one, is it normal for the pool water to smell like
5:15
chlorine? And the answer is no, the pool water shouldn't smell like chemicals because chlorine
5:21
really, you can't really smell it, and what you're really smelling, and this is kind of like an
5:25
ammonia kind of smell like the Windex smell, and you're really actually smelling what's called
5:32
Combine Chlorine or Chlorines that are in the water. This is when the chlorine combines or
5:37
binds with contaminants like sweat and sunscreen, other junk in the water, and this will of course
5:43
give off this smell. Now you have to of course do a, when you do your testing with the water,
5:50
there's a free chlorine and a combined chlorine test that you should be doing, especially in the
5:54
summertime pools that are being used, you need to do this, and they should be, there should be no
5:59
difference between the free chlorine and the combined chlorine. If you're using a photometer,
6:04
it'll actually give you the combined chlorine number. So you take that number and then of course
6:09
you have the times up by 10 to get the break point chlorine level of that. So shocking the pool
6:14
using non-chlorine shocks will take away that odor in the water and get rid of the combined chlorine
6:20
and make the chlorine more effective in the pool. So you shouldn't smell chlorine in the pool.
6:26
I know when I go to hotels, I always walk by the pool and the spa area and I can always smell
6:32
the chlorines in the water in the summertime. Not a good thing, and I think it's something to be
6:37
aware of that if you are using a pool and you smell a chemical, it's not really the chlorine you're
6:43
smelling, but it's the combined chlorine or the chlorines in the water that make the chlorine
6:48
ineffective. So it's really not particularly safe to swim in that pool because of the combined
6:54
chlorine and the actual free chlorine is really weak at that point and there's a chance if you
6:58
getting sick or ill because the chlorine is not effective in that pool. So how do you prevent
7:03
do you combine chlorine in a pool? Well, it's really sometimes difficult because if you have a heavy
7:10
use pool with people with sunscreen and other things they get into the pool from people swimming,
7:16
it's going to destroy the chlorine level. So one thing you can do before a heavy
7:21
bathing load is to put some non-chlorine shock in the pool. Prior to them swimming, maybe two or
7:27
three pounds of it and you can also shock the pool, bring it to about 10 parts per million. And then
7:32
after the party you can have the customer throw in a bag of shock or some non-chlorine shock.
7:37
And just run the pool as long as possible prior to the party, during the party the pool should be
7:41
running as well. And afterwards as well, it's something that sometimes can't really be prevented
7:48
to the degree that we want to prevent it, especially with pools with heavy bathing loads.
7:54
And it's just something that's really normal with summertime pool use. So you're going to have
7:58
some pools out there, especially if you do commercial pools, there is with some combined chlorine
8:02
in that particular pool. Here's another one and this one is a normal for my pH to rise every week.
8:10
And this is something that in plaster and pelvic dig pools, yes, is perfectly normal
8:15
for the pH to rise every week in the pool. And in our normal circumstances, the pH is going to
8:21
always be rising in the pool, these particular surface types. Now I specifically want to separate
8:28
the vinyl and fiberglass pools out of this discussion because those pool surface types are
8:33
just basically a piece of plastic and there's not a lot of acid demand created by these surface
8:39
types. They have to be cautious in a fiberglass or vinyl pool to keep an eye on that pH because
8:45
they can actually drop in those pools every week, especially if you have bathers in there.
8:49
The pH can tend to drift down. If you use trichlor tablets and a fiberglass or vinyl pool,
8:55
which I don't really recommend you do, the pH can drift down very rapidly in that situation.
9:01
So for those pools, you have the opposite effect and I should say it's a normal for my pH to go
9:06
down every week. It is in that surface type of pool, especially in the summer with usage of
9:12
using trichlor tablets as well. But for those fiberglass or vinyl pools, the plaster,
9:20
granite, pebble tech pools, it is normal for the pH to go up every weekend in those pools. Now,
9:27
there are certain things you can do to slow the rise of pH. There's water features that's going
9:32
to cause aeration, which will cause the pH to go up in the pool. If you have a saltwater generator,
9:37
the cell itself has a lot of turbulence, plus the process that's kind of the process that the cell
9:44
salt system goes through to create the chlorine also raises the pH in the pool.
9:48
And it's something that's perfectly normal that happens. If you have a newer pool that was just
9:53
plastered for the first six months, you're going to have a really high acid demand,
9:58
which means that the pH is going to rise pretty rapidly in that new plaster pool.
10:03
But just by normal standards, your pH is going to go up in those pools, saltwater pools,
10:09
much higher and faster than non saltwater pools. But it's going to rise and there are a couple
10:15
of things you can do to slow down the rise of pH. One is to keep the alkalinity around 80 parts
10:22
for a million. And this will slow down the pH rising because the alkalinity will act as a buffer
10:29
keeping the pH from going up or down rapidly. And you can also add more to the pool, the 50 parts
10:34
for a million. By doing this, you also create a secondary buffer, which allows the pH to go
10:41
to rise slower, I should say, and not go up as quickly. Another buffer that we don't talk about
10:47
too much, but it does exist. And that's the cyanary acid in the pool, specifically the cyanary
10:52
acid that's introduced into the pool as the trichlor tablets dissolve in the water. Half of these
11:00
tablets are made up of cyanary acid, which has a pH of two or three. And as these tablets dissolve
11:05
in the water, the acid is released, cyanary acid is released, and this also lowers the pH a little
11:12
and acts as a buffer to the water. And that's why in a vinyl fiberglass pool trichlor tablets may
11:18
lower the pH down to really corrosive and irritating levels for the bathers because of the cyanary
11:23
acid lowering the pH in the pool. So that's kind of how you kind of prevent a little bit of the
11:28
pH from rising. But yes, it's perfectly normal for pH to rise in a pool every week because that's
11:34
just kind of how it goes in the plaster and pebble tech pools. And in the vinyl fiberglass pool,
11:40
tends to go the other direction a lot of the times in the summertime.
11:47
Here's another one here is a normal for the salt level in my salt water pool to change over time.
11:52
And the answer to that is yes, it's normal for the salt water level to change over a, I wouldn't say
12:00
a short period of time, but over a period of a month or so, you may see some fluctuations in
12:07
the salt level. Now the salt doesn't evaporate out of the pool, but you can lose salt in the pool
12:12
from backwashing if you have a sand filter or a D filter or if you the pool has heavy use and
12:19
there's a lot of bathers and there's a lot of splash out. A lot of water splashed out of the pool,
12:23
believe it or not, when you have, you know, a pool party, you may lose like half an inch in some
12:27
cases. I've seen that before. And of course, the water will evaporate and as you're adding fresh water,
12:34
the salt water pool gets somewhat diluted in the winter time. If you have a lot of rain,
12:39
you know, 20 inches of rain, that will also dilute the water and reduce the amount of salt in the water
12:45
by dilution. So the salt water, the salt water indicator at your system, it shouldn't show like
12:52
3,400 parts per million one week and then 2600 parts per million the next week. That's really
12:57
unusual for the drop that much in a week or two. And that could be an indication that the salt
13:03
cell is failing and it's not reading the right salt level or there's a problem with the salt system
13:07
itself. Now, if you have a leak, of course, you're going to be losing salt as well. You're going to
13:12
be losing other chemicals as well. And so that's kind of how you discover a pool leak with the
13:17
salinity level, salt level dropping rapidly, the coin level dropping, you know, the pH and alkalinity
13:22
going up, depending on how alkaline your water is, you're losing cyanary gas and that indicates there's
13:27
a leak in the pool. There's a whole nother problem. But salt in the pool will change or you'll lose
13:33
the salt level should go down over time. Nothing rapidly again within a week or two. But the salt
13:40
level does, of course, from the beginning of the season in May, let's say, to the end of September,
13:45
you may see a drop from 3,400 parts per million down to 2,800 or 2,600. And that's just normal splash
13:53
backwashing, evaporation, filling with fresh water to kind of dilute the pool. All of these
13:59
contribute to the salt level going down over the course of the season in most cases. Is it normal
14:06
for a pool to turn cloudy after shocking? And this is one that yes, it is normal, depending on which
14:14
chlorine you're using, even if you're using liquid chlorine, which tends not to make the pool cloudy
14:19
because it's liquid and chlorine will just go into the water and not cloud up. But if the pool has
14:26
a very high calcium level, it can actually cause a little bit of cloudiness because chlorine does
14:31
have initially a high pH when you're pouring it in there. So if you have a really high calcium
14:38
hardness level, it can temporarily turn cloudy as the pH spike can cause the calcium carbon to
14:45
participate out of the solution. And this is kind of where you see the white cloudiness coming
14:51
into the pool. It's from that effect. Doesn't last very long, but it may last for an hour or so.
14:57
And if you're pouring in a couple of gallons of liquid chlorine, you may notice it even more
15:01
with a pool with again a very high calcium level. Again, the pH of the liquid chlorine will cause
15:09
the calcium carbonate to participate out of water a little bit and cause that cloudiness,
15:13
which will dissipate as the chlorine level kind of normalizes. Now more, it gets really cloudy
15:20
is when you're using cow hypo. And this is something that you should be aware of, especially if you're
15:24
going to shock a pool before a party like I mentioned earlier, that if you do use cow hypo,
15:30
it will make the pool pretty cloudy. If you toss in two or three pounds of it and a 15,000 gallon
15:36
pool, the pool may get extremely cloudy at that point. And this is kind of very similar to liquid
15:41
chlorine because with the cow hypo or calcium hypochlorite, you're adding a large amount of calcium
15:48
to the water at that moment. And it may be at the calcium saturation limit. And that's why some
15:55
pools you have more cloudiness than others. And you're going to probably have some cloudiness
16:01
with cow hypo and a pool regardless because you're adding, depending on how much you add to the pool,
16:06
I should say if you're adding two or three pounds, you're probably adding more calcium than the water.
16:11
Can actually absorb in this white, it gets cloudy like that. And the cloudiness may last
16:16
for a few hours. And so if there's a pool party happening that afternoon, I would advise against
16:22
shocking that pool would cow hypo use liquid chlorine. If you do use cow hypo, I would recommend
16:28
turning the pool on, letting it run for 12 or 14 hours and putting the cow hypo directly in the
16:32
skimmer. You can also dissolve it in a bucket of water. But I find that there still will cause some
16:38
cloudiness in the pool. So using cow hypo or even sometimes liquid chlorine to shock the pool,
16:44
will add some cloudiness to the pool. Now if you wanted to use a chemical that's not going to cloud
16:48
the water and those circumstances, I would suggest using dye chlorine. Dye chlorine is a granular
16:55
chlorine that's half cyanary acid and half chlorine. And this in my experience is not cloud up the pool.
17:03
So before party, you can use dye chlorine the pool safely without clouding it. Now
17:07
there are some really cheap dye chlorine shock bags that will cloud the pool up. So just be
17:12
aware of that. That the dye chlorine granular that you get in the buckets are the safest dye
17:18
chlorine to use. And sometimes the cheap chlorine, you know, you get at home depot, no matter if it's
17:24
dye chlorine cow hypo, will cloud the pool up. So just be aware that every chemical has, you know,
17:30
different manufacturers, of course. And some have more byproducts than others. And you just want to
17:36
get a reputable brand of cow hypo and dye chlorine if you choose to use that to shock a pool.
17:43
And you want to avoid extreme cloudiness in the water. But yes, the pool can get cloudy after
17:49
shocking it. And it's something that's perfectly normal. So let the customer know that you shocked
17:53
their pool, maybe cloudy for a few hours. And it's something that you have to explain because I've
18:00
been guilty of not explaining it as the customers shocking the pool and getting a message, you know,
18:05
text messaging, Hey, my pool looks really bad after you left the so cloudy, you know, yeah, come
18:09
back and fix it. Then I have to tell them that I shocked the pool. And it's a normal, you know,
18:14
byproduct of shocking the pool to clear up in a few hours. So make sure you let the customer know
18:18
that if you indeed make the pool cloudy, let them know. It's just because you raise the chlorine
18:23
level up really high and that's just a reaction with the chlorine you use in the pool. Looking for
