So I had the ten gallon but its become difficult being my first tank no sw experience just fresh decided to make my life easier and upgrade I have 40 gallons live sand and I'm getting 15 lbs of live rock tomorrow to put in now my lfs which is a sw only store and has had two guys working there the owner advised no upgrades needed besides lighting if I want hard corals and put a heater where the pump is and add two power heads which I have already on each side. Also he said since the rocks cycled there is no cycle that will happen in the tank which is not the first time I've heard that anyone else have input?
