Hey! I have an above ground salt water with sand pump pool. It has 3400 gal of water. According to my salt pump I have finally gotten my salt level where it needs to be, however, I have no clue how to test and balance this pool. We have had the pool for 2 years going on 3, and I always have the same problem.... It turns green and stays that way for a couple months before it finally clears up. This year was worse because my pump had a leak at the end of the season last year and (I being stupid) did not close it properly because I could not run my pumps. So now I have my pumps fixed and working but basically had a swamp for a pool. I have dipped out around 10 gallons of pure algae from the top of my pool since the 1st of April. I have put about 3x the normal shock-it shock (from Wal-Mart) in the pool and it is still green, although I have to say it is not as dark green as it was when I first started dipping. I ran my salt pump last night for 12 hours. It now looks like I have poured bubbles in it. Please HELP! I do not have a test kit and have no clue what kind or even how to test a pool. I am so tired of fighting this pool though! Thanks in advance to any and all help and information!
