I am about to aquascape my 110 FOWLR..going to be using live sand..my question is How much dry rock should i put in as a base?..lbs..then add my live rock..and how many lbs to start off with?..to cycle tank..
You can start with all dry rock if you want to and buy bottled bacteria to kick start the cycle. Honestly no need for live rock unless you just like the diversity of life that it brings into the tank. Unfortunately experience has taught me that sometimes diversity stands for nuisance or pestversity. just sayin.
I added exactly on small "LR" to all of my 100 pounds of dry rock. Everything in my tank now, other than corals and fish came from that one 5 pound rock.
