What Went Wrong?

[tundraSQ]

I would start here....I think it would be the warm weather and lack of filter and FC, compounded by the mesh cover letting organic matter get into your pool. Plus it would seem you had warm weather and no FC for at least a couple months brewing underthat cover. I try and get my cover off as soon as i can and get the filter going and stabalize the FC once the water gets above 50 degrees.

just took the cover off of our 16X32 AG pool (with vinyl liner and 6.5 deep end) and YUCK! Last year was green but with the help of Ben's kit and the advice here I got it cleared up and running. I put it "to bed" for the winter using Ben's advice for winterizing and used the typical black woven pool cover. It was a mild winter here in western PA and April was untypically warm. I probably should've taken the cover off then but knew the weather wouldn't stay that way. I think that cover is awful. It seems to let all the blowing dirt drift right down into the pool.
