Does a pool sand filter keep its biological qualities after you back wash it? I have read there are beads you are able to put in the filter instead of sand, is this any better?
Thank you!
Thank you!
nkI run a pool sand filter on my tank retro fitted with a sinking media works alright not as good as an ultima but does the job and no shouldn’t hurt the bio might knock off the older or dead bacteria same as k1 being tumbled. There’s several different media’s available usually plastic media takes a lot less head pressure to back flush then sand and cleans better.
