Hi all,
My first pool and TFP been helping alot. I have the PoolMath app. Details of my pool and equipment in signature.
Briefly: my pool is clear and I'm happy with the clarity. Algae not present. But it is taking me a lot of chlorine daily to keep it looking good.
My CYA level is 55. Yesterday AM Cl was 6 and 4 pp at dusk. Based on PoolMath, I put in the recommended amount during SLAM to bring my Cl to 24. I put the amount in at dusk and at dawn the level was only 19.
I'm writing now because this has happened every day: rise does not match calculation.
The Cl was Home Depot 10%. But even when I use the 12.5% from the local pool store (bottle exchange program) the rise in daily Cl does not match the PoolMath Calculation.
For my 12K gallon pool, I'm adding 64 oz of 12.5% Cl per day. This seems like a lot to me. The dawn levels are never matching the levels that PoolMath gives me.
I can understand the Home depot Cl may be weak, but I would expect the pool store version to be closer to advertised. Is there something I'm missing?
