Hi. I just joined the forum because I am tired of conflicting advice from pool stores. I have a 16x32 inground pool with a vinyl liner, approx. 19,000 (I think). Have been in the house for 20 years (the pool was there for years prior) and aside from replacing the liner too often (faulty workmanship mostly), never had any trouble. Until now. Last year we noticed a dark stain which was finally determined to be copper. Treated it when we opened with citric acid (bought online for a fraction of the price) which worked great. Then had high phosphates, treated that.
The problem is our CYA is high (140), was 180 earlier and we drained about 24 inches of water our and refilled. It came down to 120 but then I shocked with something containing stabilizer and it went back up to 140. Not wanting to drain again, and am hoping to use bleach/liquid chlorine and I know I have to be more diligent, since this week I went about 3 days without adding any and developed green algae. I guess my question is, is it okay to use regular bleach and about how much will I need to add. Today the pool is clear. Would love to keep it that way. It looks like there is way better advice here than I have been getting at the pool stores. In fact, what they tell me seems to vary within the same store, depending on who waits on me! Thanks in advance for your help! Wonderful site!!!
