I hate the scape of my tank at the moment, the rocks are all small and in need of a re-scape! The systems been running for 3-4 years. I have a Red Sea 200xl. I have live rock in the sump from the display. My question is what’s the best way to go about it I feel like buying all new live rock and replacing it all even with added bacteria would cause a crash, so my idea is if I remove display pieces like 2 at a time and move them into the sump and replace them with new pieces of rock. Would that work or still cause a crash? Would love to know if anyone’s done this before! Thank you;)
