What is DE?
EDIT: I've found out what it means. Can you choose to run a sandfilter with DE only? Or will it take to much preassure to run the water through it.
Before reading in here I thought cartridge filter was only used on smaller pools. No when I knows that this is not the case I have to look into cartridge as an option to sandfilter.
From the information I have gathered from the swedish poolforum I think 99% of the inground pools over here use sandfilters. And I can't remember that stores I have visit on the net or in person keeps them either.
I really like the fact that cartridge can filter smaller particles than sandfilters. Are there any thumb rules what you should consider before thinking of buying a cartridge filter instead of a sandfilter, in terms of size and quality?
