reebok, we have PachinkoPlayer on a short dichlor regimen to get some CYA in there.
PachinkoPlayer, that's the stuff, "dichlor." So, to make sure I'm understanding this, you got one 1lb package, and yesterday you put in about a quarter of it. You put in more this morning, I guess? This lowered the pH some, but by this evening the FC was gone again. Exactly as I had planned, bwahahaha...
Check each morning and evening, put in 1/4 of the dichlor if the FC is below 2. When the dichlor is all gone, start using bleach instead. In your pool the rate is 2 cups of regular bleach adds about 5 to your FC (until it gets used up). For comparison, the 1/4 packages of dichlor add about 10 to your FC.
Keep the FC up there until the filter stops getting gunked up, and the water looks clear. And then maybe keep it up another day or so.
