Hello,
I have a problem the pool place has been trying to fix for over 3 weeks. They finally told me to get a new pool??
Here is the problem in as much detail as possible. First time I have ever used internet to ask for help so please be kind.
Pool= 12,000 gallon
Pump = Everbuilt 1.5 HP 1.10 SQ
Filter = American Products Titan SS 24 SQ FT DE
Problem = Moved into home and the water was clear but the bottom of pool had patches of algae near main drain and other areas. Stirred up the algae and shocked pool. Chlorine level is purple on stick. I also tested chlorine and PH level with a tester using 5 drops. It is extremely high as the pool store sent me home with 25 lbs of shock and told me to dump it all in. It seemed like a lot of shock for 12,000 gallons based on what I have read? The real problem is I am unable to run my DE filter longer then 10 - 15 minutes as the pressure rises to 25-30 psi. If I backwash/rinse/backwash/rinse it drops the pressure to 18 psi and then clogs in the same amount of time 10-15 minutes.
The pool place told me once I shock let it sit for 1 hour and then vacuum to waste. I did this and a lot of green algae came out. It looked like a ninja turtle exploded on my lawn.
I took DE filter apart and cleaned each grid and put everything back together. The top filter I noticed collapsed in on itself so I bought a new one and installed it.(little screen filter at top of manifold) When I turned unit on the pressure was at 15 psi. 10-15 minutes later the pressure is 28 psi quickly climbing. I pulled the lid back off and DE is evenly coated on grids. Not green with algae. The top screen on manifold is collapsed again.
For testing I took the filter assembly and grids out of tank to see what the pressure would do. It maintained 15 psi for over 1 hour. This would tell me something is clogging the grids? Is it normal for a DE filter to clog every 10-15 minutes depending what is floating in water?
Is it safe to assume I don't have a suction side air leak as the filter maintains normal pressure when grid assembly is out of tank?
I am adding 1 pound of DE for every 10 sq ft. 2.4 lbs of DE for my 24 sq ft filter. Is that correct?
The grids I purchased a week ago. They are Pleatco 18 inch grids.
Any help would be greatly appreciated.
