Split from Adding Borax makes DE filter clogged. Zea3
Hi all, sorry to dig up an oldish thread, but I just went through the Borax process yesterday with my pool. I have a sand filter, but with DE added. I got up this morning and my pressure had shot up well over 25%. So I backwashed and the water looked fairly white. Had to have been the borax. My procedure was to take the required borax (4 boxes, since they are 65oz now instead of 75oz) put it in a bucket, and run water from the hose over it until it all spills into the pool. It wasn't necessarily all dissolved, but mostly. I don't even have a main drain, just a skimmer. Hopefully I didn't throw too much of it away by backwashing.
