So I’m picking up a 96x30x25 300 gallon tank. Problem is allot of the equipment on my 120 is gonna go on my 300 Luckily I bought everything big planning on the upgrade. Equipment isn't really a big deal, I’ve got odds and ends pumps and other random bits to keep the tank going. My dilemma is my rocks have to go in the new tank as well. Only thing I can think of is building some PVC structures so my fish have places to hide and be comfortable. Other then just stressing my fish the hell out I’m also concerned about possible ammonia and nitrite spikes and maybe crazy ph and orp drops. Anyone have past experience and advice?
