Thanks...

I have an above ground pool 27'

A hayward 1 1/2 hp pump.. I have no idea on filter. I have a sand filter..
my pump went out so it wasnt rinning for 2 mths and was thick green. I used plain bleach (per another pool stores recommendation. Then used phosfloc. Used baking soda. Quick shock not sure of brand. The pool is crystal clear but I was told at the pool store it was not holding its chlorine as it was locked up. I have since added 8 bags of quick shock and severest algae treatment which is copper based. I live on farm land and fertilizer has been being spread for the past month.

I do not have those type od testing kits. The nearest store is a walmart but they have been out of strips and testing kits for the past 2 days so as soon as they get that in I will go get one.
