I've read quite a lot on the forum about cartridge v DE v sand and there doesn't seem to be a consensus as to which cleans better or is easier to use. I'm going to be replacing my old DE this summer and adding a new pump and I have three questions:
1) based on my pool size 14,900, should I use a 1 or 1.5 hp pump
2) I've read a DE is healthier because it could filter smaller microbes and that if you have an algae bloom a cartridge makes it harder to get rid of. Is this true?
3) I've already been quoted 1300 for this. Does that sound right?
