Algae, TA or what?

[sturev]

Hi Guys,

I'm willing to help if you want it. I have a unique pool that may help prove/disprove theories???

My pool is fully insulated and covered, it stays at a constant 88 degrees and is subjected to maybe an hour or so of sunlight a month (exercise in the evenings & the sun is off the pool). I have no CYA added to the water. I would think it would be considered a heavily aerated pool, as the counter current alone creates a lot of air bubbles and then put me in there flailing around trying to swim upstream ; the whole pool is filled with air bubbles for about 30-40 mins a day.

I've only used the BBB method on a fresh fill about 2 months ago. I have added a total of one box of Borax, 1/2 gal of Acid and 1.5 gal of bleach since the refill. I run FC between 2 & 4; only have to add 6 oz every 4 or 5 days. Right now my TA is on the high side (150; was 230 on fill and I've been working it down in the last few weeks). PH is 7.8, until I add acid to bring down the TA; it takes 48 hrs to go from 7.0 to 7.8.

Let me know if I can be of any help...

FWIW, I'm keeping the solar cover on the pool now and the pH seems to be rising more slowly, not to mention the chlorine disappearing more slowly. I just wish it didn't make it feel like you're swimming in a nice, comforting bowl of tomato soup . Gotta get a solid color cover...

@ Sturev: thanks for the offer. I'll try to keep that in mind -- I'm working on some plans, now for research, writing, and PoolForum development.

@ Furbyvet: thanks for the info. Your response represents a confirmation of Chem Geek's analysis of TA and pH rise in pools.
