What you guys think? 70gal cube or 45gal cube?

If you use a LumenArc (my choice pick) or a LumenMax it will spread the light 30x30". They are "specialized" reflectors designed to spread the light evenly over a larger area. They are best used with a SE bulb, but will do ok with a DE. J&L carries the LumenArc as well, but they aren't on the site. Email them for a price.

You already have the HQI ballast, just buy one of these reflectors, and a SE socket to go into it instead of a DE socket, and pick a compatible SE bulb to run on the HQI ballast for optimal performance. Or just use your current DE socket. It's just that the reflectors will be designed for either the DE or the SE so you have to decide before you get one.

Also, the Lumenarc has two 4" ducts built into it for optional fans. You can also buy glass to use with it for DE assembly. The LumenMax will not accept glass.

thanks myka that clears things up a lot, if i go for the 70 i will definitely be doing this!

That 70g cube is a nice tank. I'm not keen on where it's drilled though, but it would work just fine. It's a great size (as long as you use a suitable reflector)!

yah for sure. im still not overly satisfied though, im not sure if i want to get the 70, or the 45, there is only a difference within 5 inch on each side. but im not sure if the 70 is the way to go or not

[Myka]

When you say "the way to go", what is making you question it?

[Trigs]

space? i gotta have it in my room, so im limited to space and also i guess the amount of time i need to put into take care of it

What about your budget? There will be a bit of cost diffference in setup and maintenance between the 45g and the 70g.

What are the dimensions of the 45g?
