Re: Can you spray Diatomaceous Earth to the filter membranes?
When I first started working on my pool, I didn't know any other way, so I dumped scoopfuls of DE into the skimmer. Later, a friend who sells DE for commercial applications told me to mix the appropriate amount of DE with water in an old, clean chlorine bucket. Put enough water to get the consistency of milk, whole or skim. Pour it into the skimmer slowly. I take a minute or two to pour in five or six gallons of slurry. I was told this method would help prevent blasting the grids with more DE than they could handle and would promote a more even application. Don't know if it works better, but that's how I do it now.
Just my opinion, but I would think your low speed would allow the DE to spread more evenly.
