We are new pool owners (just bought a house with a pool). When we bought the house (end of Feb) the pool was a nice clear blue. We kept it that way for a few months, but it seems that lately it has been more green than not. My husband is good with chemistry and math and has been reading and following your forums and trying new things, but it still is green. Here is our set up:
We have a sand filter. We have a 20,000 gallon pool. We have an aquabot jr. pool cleaner.
Our numbers this morning are as follows:
Water temp 89* (at 10:30 am)
We are out of the CYA test chemical (on order supposed to be here yesterday GRRR!), but the test strip says it is 50.
The sand filter was registering 22 psi when we moved in and has been steady at 14 lately. We have added DE (about 1.5 cups) to the filter in the past few days. It is finally back up to 22.
What can we do to get the green out so we can enjoy our pool this summer?
