Pentair Intelliflo and large pool
I am having some problems with my pool setup.
When I bought the house, the equipment was a Jandy CL 460 filter, and a very old PAC FAB 2HP challenger pump.
There was a 3-way valve to switch between filter and cleaner, and a Polaris 360 was being used.
Problems: the pump was expensive to run, very noisy, and the cleaner had many issues.
I decided to buy the Intelliflo VF, remove the cleaner, switch to a robotic, electric cleaner.
Now thats been done, and here are the new problems.
I let the intelliflo run 24 hours a day, and it seems like that flow rate is not enough for my skimmers to work effectively. The water is clean and clear, but the surface is dirty. This pool is quite large, 75 ft long, 2 skimmers, 5 returns, and I would estimate 65,000-70,000 gallons.
I set feature 3 to run for an hour a day at 95 GPM hoping that might help out with the skimming, but it does not seem to be working (been that way for 5 days now).
My regular flow rate is 45 GPM. At 45 GPM I have about 1 or 2 PSI reading on the gauge on my filter, only at 90 or so do I get the same reading that the old pump produced.
The intelliflo says my filter is dirty. I cleaned the filter (cartridge) and it still says its dirty.
Is this filter oversized for the flow rate of the intelliflo? Since its apparently time to replace the cartridge elements anyway, would I be better off getting a new filter system, and getting a slightly smaller one?
Or is 1-2 PSI enough for it to be working ok?
The water does seem to be clean.
Thanks for any advice!
