I’m not sure how to word this but I want to reshape my current rock build to a more open build, as everything is laid against the back of the tank, i beleive that there is a lot of debri hanging there and I am unable to reach it. I want to possibly break the rock as well as most of them are just base rocks to create a more spacious build for more corals, but I don’t know if I do this will kill everything due to the disturbance of the sand and amount of waste held over time, and since it’s a 20 gallon I’m more scared it will have a bigger chance at tanking the livestock, so my question is what procedure or what should I do or follow to avoid any problems?
