Well this has been going on for almost two weeks. All of the chemical levels, I was able to be where they should be, in the middle of the chart. I also had the water tested at the local Pool place. They said that my aklinity was a little low. (The DE has been going into the pool from the return and settling on the bottom and when moved comes up as a foam. I backed washed it several times a day. Sometimes 5 to 10 times. When I use the vaccum with this filter, I have to back wash the filter within about a minute or two or three. (with not much dirt or leaves at all) The pressure goes down low and I hardly have any return flow of water and also the suction in the skimmer is very low.
I cleaned out the fingers twice within 3 days of each other. The second time it had alot of DE and Alegie in there, which I cleaned out and checked the filters for rips, tears and any cracks in the top of it ir the seal. Nada, nothing was wrong it look all good. I have been running it now w/o DE and it seems to still have DE coming out of the return as a jetstream. I have added the following chemicals during this period of time: (5) gallons of liquid shock, (1) quart and a third of Black Alegie Out, (18 lbs) Alkaline Balance, (2 lbs) PH Decrease. This has been done of a course in several days during this period of time, besides (2) gallons of bleach and 3" tablets in the skimmer and the chlorine floater and the pump basket.
The was ALOT of leaves and dark green looking water when we opened the pool this season. The leaves have been taken out over a week ago and the water is starting to get bluish green but it is cloudy. But when you put some water in a clear jar, the water is cyrstal clear. ((Towards the end of last season, the pool was turning green and we could never get it back to blue))
I can test the water again tomorrow and send you the results.
Thank you for your help!!
