oooook, its been a minute since i've been on this site. glad to see its still running strong.
over the last few months i built a 2000 gallon plywood tank and 250 gallon sump. everything worked well but the sump was super sketchy and very hard to work on in the little space i had to work with. once i started thinking of potential power outages or someone bumping a valve and overflowing the sump or tank. i scrapped the sump and bought a pressurized pool sand filter.
its all hooked up and running mint, but when i try to search any info on people doing this i come up with people pondering the idea but never going through with it.
i've got 100lbs of sand in the canister, 1 cubic ft of k1 and tonight i will be adding "filter balls" to the mix (basically equivalent to filter socks for polishing water and grabbing smaller particulates)
now my question, as i've heard conflicting answers from people i've talked to in my circle and online regarding the sand part.
in a pressurized system, does the sand hold biological bacteria? i assumed the sand would be more for mechanical filtration.
second, are bio balls really useless in a pressurized system?
i know all the answers to this in a canister/hob/sump setup, but i am very new to the "pressurized" setup.
any info on this is greatly appreciated
ps: there is one company, "extreme bio filters", that converts pool sand filters for aquarium use, but they dont give much insight on the technical side other than "buy our product cause its the best"
