That sump space is lookin' good, Leo. :thumbsup: Must of taken a lot of work to get it that "sqeaky clean".
BTW - Leo, I have a question for you. Considering your experience with T5s. What do you think about me replacing my four 400W metal halides with 24 36" (39W) T5s? My tank is 96" X 36" and the actual water depth is only 22.5". Should be OK, don't you think?
Thanks Tom

It was a lot of work but keeping it like this will be easier.
I really like my switch to T5's. I have to admit I had to get used to them, but now that I found the right bulb combination I'm very happy with the intensity and especially with the spread of the light. Besides that I don't have to cool the tank and room anymore.
A few advantages are less electricity, less heat, better spread of the light. Downside is the more artificial look. Some get used to it, some don't. I would suggest to visit some T5-only tanks and see if you like it.
2x12 T5 on a 36"deep tank give you enough light and intensity to vary and tweak your bulb combination.
Maybe you should go with 54 Watt fixtures, otherwise you have some darker spots on the sides. This isn't a bad thing because lower light corals can be placed here. But it is an option because it will just fit.
To give an impression of the intensity; all my colonies are on the bottom of the tank now (water height 24"). The 7 blue+ bulbs burn for 21 hours and the 7 AquaBlueSpecial for 6 hours. More then six hours is actually too much light.
They were used to two 400 Watt AquaConnects in Lumenarcs
If you go T5, I suggest to use the
ATI Sunpower pendants. Although the finish is a bit less then the Powermodules, I actually like the design more

Ballasts and reflectors are the same, but the Sunpower has a much better price. The cooling is sufficient, especially on the 6 bulb pendants.
Feel free to ask if you would like to know anything else.
