50 lbs of LR
is a good starting point. Opinions vary regarding quantity per gallon but 1.5lbs/gal
is an accepted standard. Some use more, some less.
Refugiums have many benefits and a little reading will get you a long way into understanding them. Here is a place to start: http://www.drsfostersmith.com/pic/article.cfm?aid=439
I only vacuum fish waste off the front floor of the tank. The remainder of the tank is an entanglement of caves, cliffs & various hiding places for fish and inverts.
If you want the "most colorful rock" that you can find - don't buy it over the internet because buying rock that way is like buying a pig in a poke. I've bought LR
from 3 different sources and was very disappointed in most of the rock I received. None of it looked like the LR
that was seen in the advertisments. However, its always possible to get lucky and get some nice rock at a fair price over the net. You may want to try your LFS
's and pick out a piece at a time when you see what you want. It's more expensive but you get exactly what you want as far as shape, size, configuration, coraline coverage and occasional hitchikers.
