is it ok to have ceramic rings for biological filt. and base rock back in the filtration chambers. i just loaded up some base rock to replace my rings but im curious to know if i should leave the rings in for a couple days just to make sure the rocks alone will do the trick. i have a poly filter in there as well for absorption and a carbon bag as well. i left in one stock sponge and removed the rest.
so leave in for a while or get them out? what do you guys think?
