The amount of DE yous actually need is an arguable point amidst puddle guys. Some say add more and backwash less, others say add less and backwash more than ofttimes. We like to side with the "add less and backwash more" group. One matter almost all agree on, is that the manufacturer's instructions that come with most DE filters always recommend putting in Manner TOO MUCH DE. If y'all put too much in, you risk clogging the filter, straining your pump and significantly reducing your circulatory force per unit area in the puddle.

If you have a Sand filter, you well-nigh probable accept a Multiport on it. Just follow the aforementioned directions as above with the exception of adding the DE. You lot will non demand to do that step.
