New Intex owner from Texas

Hhhmm. Is there a non-liquid pure chlorine format that I can use instead of bleach? The granules seemed easier to store and apply than liquid jugs of bleach, and I'm not sure the bleach is cheaper. My pH has been a steady 7.5, and I had been adding about 1/2 cup of granules every other evening to keep the OTO dark yellow. The SWCG runs for 4 hours at night.

And if I go a pure chlorine route, how much more CYA should I add? I had been doing a pound at a time via the sock method, until I had added the full 4 lbs ... I don't remember how much that raised me to, I can't find my notes. We have had rain this summer, unusual for Texas, so I know I lost some CYA from pool overflow.

In the sense of "pure pool chlorine" -- there is no such thing. Even pure chlorine gas is (I'm simplifying things here) is functionally 1/2 pool chlorine and 1/2 muriatic acid.

The 'purest' pool chlorine, in the sense of fewest side effects, IS bleach.

If your pool store sells liquid chlorine (10 or 12.5% sodium hypochlorite) that is the same thing as bleach but at a higher concentration. (Bleach is 6% sodium hypochlorite.) It may be more convenient for you as it would cut down on the number of bleach bottles.

:-) Allright then, my bad for not being clear. I meant 'pure' as in what vendor carries a granule based chlorine pool product that has the least amount of other chemical products in it (calcium, stabilizers, etc). In my case, I have to store the liquid bleach in the garage, and I either have to carry it through the house (most direct route) or take it outside and around the house (more convoluted route). I was not as concerned having to carry granules through the house as if I were to spill them, I could vacuum/sweep them up. Liquid bleach would be a disaster. I can't store the bleach near the pool.

I don't think there is a form that fits with what you have in mind. Cal hypo (~68% chlorine) adds calcium; trichor (~90% chlorine) adds stabilizer.

If you can't put a lockable storage box near the pool . . . I don't know what to tell you.

I keep my jugs of bleach in the utility room in my basement where it is cool. When I need a jug, I carry it up a flight of carpeted stairs. In all the years I have been doing this, I have never had a drop of bleach leak from a jug. Just my $0.02.

Thanks, WM.
