Hello all... I'm new to the forum and also fairly new to having a pool.
I have a serious Algae problem. I'm at the point that I want to close the pool for the rest of the year. I had the same issue last year. I've been living in my house for about 2 years now. So, I assumed the previous owner never replaced the sand in the filter and I was told my pump was too slow (3/4HP). Therefore this year I replaced my Hayward pump & sand filter to a new Hayward 1.5HP super-pump and a new S220T Sand filter with new sand.
At 1st I thought it was some of the tree branches that were hovering directly above the pool. I hired a tree guy to cut all of them down. I thought that would fix my issue, but unfortunately it didnt. I've been trying to elleviate my algae issue by continuously shocking the pool and taking my pool sample to my local pool store. Last night I put in 3 gallons of regular 6% ultra liquid bleach. I just took it this morning and this is the readout they gave me:
FC = 6.7ppm
PH = 7.6
Hardness = 0ppm
Alkalinity = 63ppm
Cyanuric Acid = 25ppm
Please somebody tell me what am I doing wrong... HELPPPPPP !!
