Here is what I did with it I did change who goes where though. My "future seahorses" (kuda) will go in the 65g and my current ones are in the 75. I can't wait for the macros to grow in nice and lush. I ordered a 48" 4-54w HO T5 light fixture for this tank. (1-65k 1-10k 2-actinics) I also purchased an extra 10k lamp just incase it's too yellow for my tastes. It will be here this week Then my macros should grow like weeds!
