Had a question about low CH in a fiberglass pool.
My pool is under construction. I am going to be doing the concrete soon, and plan on draining, polishing, and re-filling the pool after it is finished (only costs ~$11 to fill 13.7k gal). With that said, I don't want to invest too much money into chemicals, before that happens. So far I have raised my CYA up to 35, and am keeping chlorine in it (6% bleach). But my CH is low @ 60 (Testing with TF-100).
My long winded question is this... How long can I get by with that without damage? I plan on having it complete within the next month.
