We have a bunch of DE that the old owners left. What is the equivalent for the BBB method? Just wanted to hopefully re-use some chemicals that the old pool owners left us..

You only add DE after you backwash or teardown & clean your filter.precator said:loughps said:The BBB equivalent for DE is DE. You can keep that and add it to your DE filter as you backwash and need to.

When do I know if I have to add the DE?
