So, an issue has come up that I didnt anticipate. I have a friend that is upgrading from a 90 gallon tank to a 180. His 90 has that same footprint as my 75 I think and he is willing to give it to me. It is reef ready. It is in better shape than mine and has less scratches in the glass. Problem is I wont be able to have it for about a month until he gets the new tank and gets everything switched over. I am well into the cycle for my 75. What should I do? Finish the cycle but don't buy any livestock until I can switch out the tanks? or buy stuff and switch it over? Going to be hard not to buy anything once the 75 is cycled, but I will be much happier with the 90.
