I have an above ground pool that holds 10,000 gallons of water. I have a sand filter. I have had it for 3 years and it stays green most of the summer. We have had lots of rain this summer and very hot, humid weather but I just don't understand why I cannot keep the water clear.
I had a pool a few years ago and all I ever used was shock it and baking soda. It never turned green and was always sparkling clear. We filled the pool from pond water so it was very yucky for about a week but then cleared up.
This pool, I filled from my personal well water which was perfectly clear, but it didn't take it long to turn green. The water hardness is always low but I had read that the water hardness did not matter if you had a vinly pool. The total alkalinity is usually low also.
I have muratic acid, but have always been afraid to use it.
Help, I want clear water!!!!
