14 Chlorine

This is Janine with pool zones, and we are up to number five which is chlorine and we balanced all the other tests that we need to balance, and we’ve added the right chemicals, and we’ve added small doses of the chemicals. 

Now, let’s talk about chlorine and I’m going to use this particular video which is made by swimmingpoollearning.com this guy here, his voice is just so familiar to me, I’ve listened to this guy so many times.

Listen to his voice…. (audio)

Now he’s going to get into a lot of technical jargon which I’m not going to get into right now. But here’s what we do, if it’s a normal chlorine pool, even if it’s a saltwater pool we still install one of these Chlorinators onto the plumbing line at the pump and filter. 

And in there we place a three inch chlorine tablet, you can see here he is going to use a pair of child locks to undo this lead because they do get very difficult to take off. Now there’s the three inch tablet, and he’s going to take the lid off and he just puts it in there. 

Now there’s one problem with that, I’m going to talk about that in a moment, see where the hose is down the bottom. And if you look at there’s a hose in front and there’s a dial, which he shows. 

So, in goes the three inch tablets, the water goes in there and it dissolves the tablets, you just think about this for a moment, look where the host is down the bottom, there’s a dial there. 

You turn the dial and you set the dial on the setting that you want to set the dial on. Once it’s set, then of course, it starts to allow chlorine to seep in and dissolve into the plumbing line. Here’s the problem, look where the hose is down at the bottom, the water’s going into the bottom and then it’s supposed to go into the plumbing like and go into the pool.

We don’t do that, we take that hose, which is connected down below, and we connect it up to the top. So what we’re doing is we’re connecting up to the top of the chlorinator, not down the bottom so we send the water up the top, think about that. It runs down the tablets and it dissolves the tablets so we’re using gravity in effect to dissolve the tablets.

Here, they’re relying on the water, raising itself to the upper level. The only problem is, with that, if there’s any air lock which we’ve found so many times with the factory default setting, that the chlorine tablets will not dissolve. So if you have one already installed, make sure that it’s installed with a longer hose to the top. 

Now, there’s a dial here. The dial is set, you set the dial, it’s between one or zero to five, and just set it at, maybe two and a half initially. See how it is, do your chlorine checks, and with your strips or the drops and see how much chlorine you’re getting and then adjust it. This is going to be something you will learn to adjust. For example, you have a lot of bathers coming into the pool, your it rains the day before, there are a lot of leaves in the pool, okay that means you need to turn the dial up maybe to four or five. 

You don’t have anybody, it’s getting it to winter. You’re not heating the pool. There aren’t many leaves around, turn it down. I think you get the message and you get the idea. 

So, put the chlorine tablets in the top, adjust the dial to a number, and then validate how much chlorine is actually in the pool by checking with a drops or the strips.

Now remember, I spoke about this before, there are two types of chlorine out there, you should know this by now, there’s the total chlorine, and the free chlorine. And the reason there, we see the two is that if it’s total chlorine, you should know this, that it’s active, it’s working, but it’s been attached to some form of algae or bacteria or something that it’s sanitising, that’s what it does. 

The free chlorine is available to sanitise and to do work. So in other words, you have to have the labourers that are doing the work which is the total and you have to have some free labourers to actually start new work and that’s what’s going on here. 

Again it shows you the ranges so you just want to make sure you’re within those ranges to be safe, and I think you can, with very clever settings, get it down to one part per million of free chlorine and swimming lower level of chlorine. And make sure that your total chlorine is sort of in balance…. or balanced I should say, by that what I mean is if your total chlorine happens to be for example, let’s go back to that total chlorine happens to be say 10 and you have… 

I missed it here, hold on. Let me go back, let me see if I can get back that screen I was looking at a moment ago, there we go. 

So say the total chlorine is something like 10, but you have zero free chlorine, you have a serious conflict going on here. So let’s go to something more normal; say total chlorine is three, but you have zero free chlorine, you need to turn that dial up. 

So the critical one is get that free chlorine between one to three PPM’s and everything will work very very well. Now, the next video, I’m going to discuss what happens when the alkalinity starts to get out of check and what to do about it. 

So let’s delve in to the next video which will only be on one subject and that is;

What happens when the alkalinity starts to drop below 70?

What do you need to do about it to get it back in balance?
