Well I've got an extraa eheim 2217 I've been running with nothing but filter floss, and the occasional bag of cat on in, but recently upgraded my Skimmer so have I have no more need for the floss... now the eheim sits empty, and I've been looking for ways to utilize it, and was thinking about filling with live rock.
I've read mixed reviews on whether this is helpful, or detrimental, and can't make up my mind, so was hoping to get some input... I know that it can be a detritus trap, but was thinking about wrapping the input to the filter in a sponge to catch any large pieces of detritus and giving my CUC something to munch on in between cleaning it.
What would be the pros/cons of filling this Eheim 2217 with live rock? Its a large canister so could hold quite a bit.
Its going on a 125 gallon FOWLR
with a 40 gallon sump. Its got about 150 lbs of rock so far, and has been running for over a year. The Bio load is still very low, but will be higher within the next few months.
Thanks in advance for any input! Any, and all advice is welcome!!
