Question about Bio-pellets?
 

Is there a time when all the bio-pellets in my reactor should be completely replaced? They seem to be breaking down, and i know they're suppost to break down, but they're causing a large build up of material in my connecting hoses, sump, and on all the pumps running in the sump. I've been adding, but should they be completely replaced now and again?

nope, just keep topping them up. the build-up is bacteria mulm, i think if you use the Zeovit product biomate it may help get ride of that
