Okay so I want to make more space on my sand bed and the best way for me to do so is by removing some rock. I'm worried about by me removing the said rocks I will cause a problem in my tank. I just finally got everything perfect, corals are growing, they are coloring up nicely. Do you think there will be any problems at all? The rock I would be removing is maybe 2-3 lbs but it is buried a little bit under the sand. Let me know what you guys think.
