I've got a fairly new 55 gal
tank that's been established for better part of a year, with the recent addition of about 120# of LR
a couple of months ago (which has settled in quite nicely :-) I love the rock, but admit that I may have gotten a bit too much. Not for the fish's sake, but for mine -- it's tough to get between it and the glass in several places to clean, and there is not much open area on the bottom (ie, that I can reach to clean) between the rocks for substrate critters.
Sooooo.... I'm wondering what it would take to upgrade to something like 120 gal
. Obviously, I'd use all of the existing water, substrate, etc -- but how best to make up the difference? Once the new tank is in place, would I simply add new substrate and freshly mixed water? Or would I have to cycle that much water (65 gal
) first in a another tank, and THEN add it to the new one?
