Newbie to pools

That spot in the pool has a weird zig zag in it so that is why the measurments don't make sense. There are stairs there so the number of gallons lost by the bad measurment are gonna be small so that's why I didn't worry too much. I just turned the entire pool into two rectangles one for the deep end and one for the shallow, found the areas and then subtracted the two big triangles empty spots from them. Multiplied the areas by what I considered the average depth over that section and then converted to gallons. I figrued the little pieces on the edge and whatnot wouldn't really matter to significantly overall. I thought about drawing it up in Autocad but I had just deleted it from my computer as it was killing it. I'm an engineering student so I'm pretty good at math but was kinda curious what others would come up with. Never hurts to double check with someone else. I apprecite the time you spent helping me out though. You ever have any questions about cars or engines I can for sure help you out there. I'm a member of quite a few car and truck forums, this pool stuff is just new to me.

Yeah, it's been a matter of some interest to me how many new members here share that involvement.

You talking about Involvement with other forums?

Do you know what a ballpark dose would be for getting the pool to 12-15ppm?

[PoolDoc]

Yes, involvement with other AUTO forums.

On a 11,000 gallon pool, a gallon of plain 6% bleach adds about 5 ppm. So a 15ppm dose would be ~3 gallons.

Well at least one now, lol. But I'm sure there are more. I take care of all the friends and families vehicles and I know what a great asset forums can be. Learn the majority of my stuff from them.

And thank you for the info. Just found out that the chlorine from the pool store is quite cheap after the initial purchase of the container. Aboout $2/gal for 11.5% chlorine.

Yeah, that's a good price for bleach. I think it's cheaper in Florida, than in most other parts of the country.

A couple of cautions:

1. Bleach is corrosive, but commercial bleach (above 10%) is very, very corrosive. Make sure you do not get ANY on what ever you carry the bleach in. You can lose a truck bed to a drop of bleach here, and a drop there.

2. Bleach doesn't store well in warm weather. At 90 degrees (when the BLEACH is 90), it can lose a LOT of its strength in just a week. If the bleach has a little iron in it (it often does), you can turn 12% bleach into 6% bleach very quickly.

3. For the same reason, try to buy bleach within a few days (1 - 2) of your supplier's delivery and then -- ideally -- add it to the pool immediately.

4. If you need to store bleach, it will last much, much longer in a air conditioned room than it will in a hot garage or pump room. It doesn't fume (well, it gives off oxygen, when it deteriorates), so there's no odor and no chlorine gases. It's just the drips that are a problem.

I've noticed that a lot of pool trucks have the beds completely rusting out on them. So it looks like I am gonna have to buy 2 1/2 gallons at a time and store half of it for a week.

But just thought of something. If I'm keeping the pool at about 3-5 ppm with the TC won't I only have to raise the chlorine about 10-12 ppm using liquid chlorine? So then I would only need a little more then a gallon of the of the 11.5% chlorine weekly? You think it would be ok to assume that I can use a little over a gallon for the first week and then just the rest of the chlorine the second week because it has degraded. I mean i would test it afterwards but I'm thinking it should be close, might not be enough though.
