My IM 75 ext after swap from 60 cube. I love the tank! been 5 months and still battling a little cyano on bed but it's slowly receding. I need to get some more coarse substrate because my gyre really moves some water and my gold head goby is constantly moving sand which blows with the current to the left. I have a mitras LX7 with 4 bulb T5 hybrid but the hybrid is 24 in, so i ordered a couple of the new version Noopsyche K7 pro II V3's to compliment the mitras and i'll pull the T5's.
looong way to go before I'll be happy, but i think it looks nice so far.
