Hi all I've had my 55gal. tank up & runing with about 50 lbs. for 4mos. I have a hangonthe back fillter and a protine skimmer. I just added a wet/dry about 3 weeks ago the guy @ the fish store said to start taking out the bio ball in about 2 more weeks, about 2 hand fulls a week and start to replace them with little pices of live rock is this right? he said if I leave the bio ball my nitrate will go thru the roof?
He is on the right track and offering modern advice.
The theory is that bioballs get neglected and need to be cleaned often, say at least twice a month. Problem is they stay put for years on end and fill up with heavy detritus. LRR is the new theory. I run it and have been having good success. It can still trap particulate waste but the idea is that critters will break it down unlike the no critter aspect of bioballs.
So do bioballs create nitrates? No. But neglect does.
It is true that an increase of nitrate is linked to bio-balls however not that quickly. The issue has to do with whether the bio-balls are getting enough airtime or not. The wet/drys where the bio-balls on the bottom are constantly submerged is where their tends to be a problem. I'm not sure of the specifics on that problem. a drip wet/dry seems to be the best. In any case, the customers coming to where I work that have this nitrate problem have had bio-balls just sitting for maybe 2 or 3 years. As caferacermike said, neglect is the issue. Not so much the bio-balls.
