can I have a flat piece of rock with holes in it against the back of my tank, or is that just asking for dead spots??? I've got this neat piece of rock (not live) with a bunch of holes in it that would fit up against the background. I'm just not sure if that would work. I have the jbj deluxe 12 gallon, and I put in a maxijet 900 in place of the stock parts for water flow. Also, are there some kinds of rock not suitable for reef? I know some will grow corals and stuff better, but I just want to make sure there aren't kinds that will leach into the water. The lfs said it would work fine, but I'd prefer a second opinion since they couldn't tell me what kind of rock it is. It's a light colored rock and not grainy... I could post a pic in needed. Thanks for any input!
