How Low Should You Go?

Thanks!

My ph was below 7 when I tested after pulling the cover off.

So you think it is about 18,000 gallons? It's 3'6" on the shallow end then at about 8 feet it slopes down to 9'6". My public school math skills calculated around 36,000 and that's what I've been basing my chemical applications on. Krikey!

Thanks for the advice!

It may be 24 or 25,000 gallons, but it's hard to say. 36K sounds really big. Excessive chlorine can cause liner issues as well.
