Hey yall! I bought a house with a pool 1 week ago & I have no idea how to take care of it. It turned green the second day I had it. I shocked it & spent $250 on ph up & conditioner @ the pool store & would rather not give them anymore of my money. SO... What do I do now? I know I need a good test kit, but which one exactly? I have an old basic 5 test kit I found in the shed, & some 10% chlorinating liquid I picked up. What should I do while I'm waiting on the test kit? I don't want it to turn green again!
