Filtering large aquariums, is crystal clear water possible?
After about a month of running my 125 gallon I just can't get the clarity I have in the 55 (fluv 306). Biological filtration is there but the particles in water are very upsetting. At the moment I'm using diy sump setup in 20 gallon long. Water from the overflow goes through 2 compartments pictured, where it first hits the blue/white filter pad and then pot cleaners. I put a marineland HOT with micron cartridge on the sump as well in attempt to clear the "dust". Two heaters in sump turn on quite often as I try to keep the temp at 82F , and as such I think that the mineral buildup created is contributing to dustiness. Perhaps putting heaters in a conpartment could help, but after a month of running I also see good amount of sediment on the buttom as well...
Now I wonder if it is possible at all to achieve " dust" free water in larger tanks? I'm tempted to abandon the sump altogether for a pair of canisters, but I really like the minimal equipment look in DT. Sigh.
