Thanks for the response, Mike.
I am in the process of adding shells to my 180, and having been in this hobby for many years my first thought when adding anything to the tank is how will I clean it. It seems to me that the type of shells (as well as numbers) we use for shelldwelers have got to be very efficient at trapping detritus I/S them. This being the case, how does one go about cleaning the I/S of the shell?
Has anyone experienced their water quality going down hill due to this build up? We know that tanks can suffer greatly from detritus trapped in the substate and rocks as well as dirty filters, then how do we keep the shells from accumulating detritus just like these other things?
