| Re: Bio Balls, is this really why??? i just wanna add that my wife (polkadotcat) works at the zoo here in texas, and every single system they have their has a sump that consists of a 10 - 15 gallon bucket, a crap load of bioballs and a return pump.
theyre been running this way for about 7 - 8 years from 30 gallons to 1000 gallons... but then agian they do FO tanks. |
