Did a chat with someone on a pool site..

ME: Regarding pumps / filters.. I read that the typical pool places will try and "throw in" a free pump upgrade to say 2hp or what not.. I read that a 24' pool shouldn't have more than a 1 hp pump and that a bigger pump is actually counter productive as it pushes water through the filter too fast.
THEM: Depends on the filter media
ME: Sand i'm going with.
THEM: Sand works better with a fast flow, cartridge and de does not
So is he full of bologna?
