Hey everyone --
I've got a 55 gal
tank with cc
that's been established for over a year, and the cc
substrate is finally hitting my limits. The basic problem is that I've got [dare I say] too much live rock -- about 110 pounds in a 55 gal
-- great filtration, but makes it really tough to clean around the edges between the rock and the glass. As a consequence, I'm constantly fighting the nitrates. I'm planning an upgrade to a 120-ish tank with sand which will give more room for critters, but I'd like to make the switch to better control the nitrates sooner than that.
Soooo, how to proceed? I already have 20# of Arag-Alive, and was planning on another 40# of regular un-live aragonite. Now, I've read (and seen pics) of the latter just clouding up the tank and taking days to clear up. Is there anything I can do to minimize that? Perhaps pre-rinsing to rid of the finest particles (seems contradictory to what I want the sand for in the first place, however). Or just suffer through the cloud? If so, will the fish/corals (softies only) be OK? Perhaps pull them out into a separate tub while the sand settles? I would assume that since the one bag of Arag-alive is already wet, that I might be able to simply lay it on the bottom without too much disturbance?
Ideally, I think I would rather change out half of the cc
at a time to minimize the hit on the bio filter. But if I need to either move everything to a separate tub, or suffer a through a three-day cloud, I'm inclined to just do it once. Perhaps bag up the CC
in a filter bag for a while so it's easily remove once the sand is seeded?
Any thoughts/advice appreciated.
