How big can I go while keeping the same light?

I personally wouldn't go over 20-22" deep with a 150W, but that's just me. A 20x20x20 or 22x22x22 cube would look pretty sweet.

FWIW - On my 37 Cube (18Wx20Lx24T) I am running 250Watts, I almost wish that I bought a 400W as I find the light intensity really drops off about half way down the tank.

Hmm, I think a 20x20x20 would look cool as well... but I am wondering if the light would penetrate well, seeing as this is in a flood lamp . I don't have a big reflector using this.. hmmm... I definitely want to be able to have a good penetration for SPS and such.

Well, two things come to mind... 1) You don't have to have your height the same as the footprint dimensions. I.e., maybe 24x24x20 or something like that. What height is your 20g right now? Or do you want to go to a higher tank anyhow. 2) If funds are an issue, maybe get the tank first, but budget for a light upgrade in the soon after. I'm sure the light would at least bridge you over the interim.

Hmm, well I am not too sure of the height of my 20g. I do know it's just a standard 20g, but I still don't know the dimensions

The height.. I'd like to make a little higher than what I have now.. maybe a few inches higher.. that's about it.

Funds are not so much an issue if I can do this without the light upgrade haha. I just wanted to keep most of what I have for the most part...

Can you guys help me out in deciding where to go to get the cube built? Quality and price.. and does anyone know how much the cost goes up if I wanted to use starfire on the front pane??

Sorry for all the questions

Scott, talk to Dennis when you decide what size you want. I think they are backed up a bit in tank building though. (We were talking to Albert about tanks the other week)

If you are doing this primarily for fish, I would suggest a longer tank, because your fish will be much happier with more swimming length before having to turn around. Say a 4 footer. Then Put your HQI in the middle, and have a large rock pile in the middle with your SPS corals on it, right under the MH.

Then just run cheap fluorescents over the rest of the tank, like a FOWLR. This way you only have to spend a little cash on some strip lites, and you will utilize your MH for your light demanding corals in the middle of the tank.

This would be a good setup for future expansion too, you could add a second MH bulb anytime, and make the fluorescents actinics.

But it depends on how much room you have, maybe you dont have 4 feet of space. Just an idea for you.
