Diatomaceous Earth
How do I use Diatomaceous Earth, when back flushing the filter?
Our pool is green with algae and dirt. We just cleaned out our 36sq ft DE-3600 filter. We added 9 cans of Diatomaceous Earth as the instructions said. We then added 4 gallons of liquid chlorine, and ran the pump for about 1 hour. The pressure went up to a 25 and I know its supposed to be around 10-15. Do we need to back flush the filter? If so do we add more diatomaceous earth? Thanks for your help.
back flush the filter then, with the filter running, put handfuls in the skim filter just make sure not to dump it in, the water going into the filter should look like water downed milk and not be "clumpy" the box of D Earth should tell you how much you need to add, make sure to allow the filter to run for at least 45 minutes after you add the diatomaceous Earth so it will properly adhere to the filter surface
make sure that when you are adding the D Earth that the filter is only pulling from the skim filter and not any other source like the bottom of the pool or the intake that the pool floor cleaner uses (you know the little guy who cruises around on the pools floor and picks up dirt and leaves)
