I have a very small in ground pool, about 15,000 gallons and approximately 12x24. I recently converted to saltwater (with a Jandy product), and I have a cartridge filter (which I hate, if it gets the slightest bit clogged it makes the satwater mechanism turn off). I always planned on switching to a DE Filter (although I plan to use an environmentally friendly chemical subsitute), but my pool guy talked me out of it. Big mistake! My question is, because my pool is so small, can I use an above ground DE filter like the Hayward EC50? Any and all help is welcomed!
