Should we do a sand or try a cartridge filter?

[CarlD]

One of the neat tricks we've learned is that if you add a little bit of DE to your sand filter, it filters much finer stuff. I use less than 1 cup of DE. You add just enough to raise your pressure about 1 lb. It can be anywhere from 1/4 to a full cup. You add more after you backwash. DE is amazingly cheap when used this way. I'm not even halfway through a 10# box I bought last summer for $8. I MAY finish it this season, but the results are incredibly good.

how do you add the DE?

Mix the DE in a pail of water and slowly pour into the skimmer. Let the pump run for about 20 minutes for the pressure to stabilize. Add more if necessary, wait again, to get the 1 PSI increase.
