Hmmm. I will check out the DE. A friend suggested adding cellulose but I"m not familiar with that. I posted pics under another post under 'pumping'. Will it be too much to add pics here too?
Pic's are always good.
Cellulose fiber on top of your sand filter will give you a little extra filtering ability. Cellulose seems to be a viable replacement for DE, and it's non-toxic, and its biodegradable. It is purported to filter down to two microns where DE filters to four microns. Don't forget to replace it each time you backwash though.
I use it in my filter after all the spring tree junk and cottons are done. Others on here have stated not to use it in a cart filter but there are dosage instructions for sand and cart filters. It puts a "polish" on the water and I have never had it drive up my pressure.
