    DE

    How much DE should I add to my pool, 22,200 gallons, after cleaning my filter?

    It's not the size of the pool, it's the size of the filter. Look for a label on it somewhere, something with brand name and numbers, and we should be able to help you figure it out.

    If there's no readable label, then it's going to take pictures and dimensions to figure out what you have. If you have the filter apart, measure the size of the grids; that can also help identify the filter.

    Well, there you have it! 9 lbs, if you've disassembled it and done a good scrubbing. If it was just a backwash, then 80% - 7.2 lbs. A scale is the best way, because the volume depends a lot on how hard you pack it.

    Thx, if it was a snake it would have bit me! Is the best way to apply it is through dissolving in water first?

    Yes, you can mix it in a bucket of pool water in small batches. Don't try to add all 9 lbs to a 2 gallon bucket! The mixture should be milky without clumps.

    You can also slowly dump scoops of DE into the skimmer while the pump is running. Be sure and remove the skimmer basket first and make sure the pump pot strainer basket is clean and in place before adding the DE.

    Some people mix a slurry in a bucket and pour that slowly into the skimmer. I usually just dump it a little at a time into the skimmer and let it break up and get sucked away by the turbulence. You just don't want big clods of it blocking the pipes.
