A few months ago I bought a 75 off of some guy...the tank was in desperate need of some TLC. With what he was asking, I couldn't pass it up. To make a long story short, over 300lbs of Fiji LR was included in the deal. The tank was running for 3 years. The problem is that he was using tap water and NEVER did water changes. All he did was replace evaporated water with more tap water. He also only had two PC lights over them.
This rock is now in my 75 with RO/DI water with 10% weekly water changes. I have 2 175 watt 10k coralvue reeflux bulbs and 2 96 watt PC actinic. It has been in the tank for about 2 months. My ? is that the rock has no coraline on it. It is dark brown but I think has contributed to the brown sand I have developed in the tank. Stupid me used his sand as well, which I will be replacing this weekend when I take everything apart. The rock looks very porous and has many sizes and shapes to create an awesome aquascape. Will it be ok? Any suggestions?
