Anybody have some experience and or thoughts on how high to the surface you really want your live rock. In theory your SPS corals are growing to grow towards the light so if you have live rock to close to the surface it won’t take long for them to grow right to the surface. I have seen a lot of tank pictures that have corals growing right at the water level. Would it be better to keep you rock lower in the tank know that space will be absorbed by growth, and if so how far down the water column should you go????
