having trouble with a cloudy pool

[PoolDoc]

If you would, fill out the chart, so I can advise you better: http://pool9.net/pf-chart/

Also, tell me how your water *looks*.

looks dark and still a little cloudy. I can finally see the bottom at the shallow end, so that's good.

Color?

[adambeazley]

Blue, but still cloudy.

+ Run your filter 24/7

+ Only backwash on a 4 psi or greater pressure rise.

+ Add 2 - 4 cups of DE filter powder (Lowes, Ace, Home Depot, Amazon) to skimmer after each backwash. Watch for rapid pressure increase. Discontinue when pool is clear.

? What size filter do you have?

[adambeazley]

TR-140 with about 900 lbs of pool sand. Its a big one. I did just change the sand and rebuilt the pump about 3 weeks ago FYI.

So I noticed that there is DE filter powder for DE filters and sand filters... Does it matter which one i get? The one you linked to is for DE filters? Does it matter that i have a sand filter?

The DE that is used to test to see if sand filters are working properly is the DE that is normally used in DE filters. One and the same.
