Just an update... I CAN SEE THE BOTTOM !!! Wooohoooo. No more debris on the bottom. It took awhile but it totally cleared up. I think it would have probably cleared up faster if I would have cleaned the filter a little quicker and re-coated the DE a little more often. I have the FC around 4ppm as of yesterday. Also the pH was @ 7.0.......time to raise the pH. How much should i add @ a time till I get it to 7.6 ish?
