hello all. still attemptting to clean up /open our pool. when i have it set to recirc, the pump blasts great, amazing flow and really moves the water. when i shut it down, switch to filter. i can immediately tell that the flowrate is lower (to be expec tedwhen filtering) but after about an hour its very noticeably slower, i accidentally fell asleep last night before switching back to recirc as im gone all day for work...when i got up, the return was barely moving any water at all and the pump was warm to the touch. my question is roughly how oftern will a sandfilter need backwashed while trying to remove dead algae? i know it depends on level of algae, but i feel like i should be getting more than 3 hours out of filtration before it starts slwoing down horribly.
secondly should i keep backwashing and simply work through it?
last lil b it of info, before i got the filtration up and running, i did empty out the stagnant water in the sand filter and inspect the sand... it wasnt hard or solid
