Well I'm glad you guys like it, I'm not happy just yet. The 4 ft light is pissing me off and I'm not happy with the rock work yet. In the next week I will be putting more rock in and getting my lights from a local guy. I have about 120 pounds in the main display and 60-70 pounds in the sump. I will be adding around 50-75 pounds as well in the main display. I will be buying 4- 36" T-5s to light this thing should be plenty for what I want.
