The following was written:
"Flocculants or sequestrates aid in the filtration effectiveness of those filters by prematurelyloading the media to affect smaller micron filtration.
These helpers are not recommended for filters using cellulose fiber because it already naturally filters much smaller particles, in some cases down to 2 microns. The sequestering chemicals can quickly reduce water flow in cellulose fiber filters below acceptable limits, and will cause a rapid increase in filter pressure. If these chemicals are used in cellulose fiber filters, a gray jelly-like film will form on the filter grids, blocking water flow and severely reducing the filter’s effectiveness. In addition, the use of these chemicals will often cause the cellulose fiber to cling to the filter grids or cartridge, which serves to impede the backwashing/ cleaning process. Under normal circumstances, cellulose fiber will backwash completely from the filter much more quickly than traditional media"
"Mixing with D.E.
Pool operators should be aware that cellulose fiber is never to be mixed with Diatomaceous Earth filtration media. The two materials are not compatible and, if combined, will severely restrict water flow and raise filter pressure."
As I have no personal experience with cellulose does anyone have any thoughts or opinions, or better still personal experiences, especially with sand filters?
Thank you to those who respond.
