Deep end? Would need to know gallonage. Also the Free chlorine AND the total chlorine. Other test would be good too.

You need to be keeping an eye on Calcium too.

You mention in another thread about chlorine also. Other chems don't look too bad and if I was going to do something here I would go grab 1 and in fact probably 2 gallons of chlorine and walk around the pool pouring them in. See what it looks like in 4-6 hours.
