4ft light 6ft tank

Will a 4 foot light fixture work on a 6 foot tank???
We are trying to figure out if it is good enough lighting

Nope. Did that when we got our first 6' reef tank & it was BAD. Nowhere near enough spread or light for the 6' length. Don't waste your money. Just save up to get a proper 6' light. In general, each MH will do a 2' spread.

I would say it depends.

If you had a 10x54w T5 you could hang them high enough to give you enough spread.

It also depends what kind of tank you want. Jam packed with SPS, a mixed reef, softies ect.

I run 6x54w over my 5 foot tank. I have no problems with a clam on the bottom or sps, and I also have shaded areas on the sides for other corals. Personally I like a bit of uneven light vs the perfectly lit tanks we often see, but again it depends what your goals are.

With MHs it works less well since MHs are spotlights, but who uses MHs these days anyways :lol:

A lot of European tanks use a shorter fixture than the tank - go on some European forums and you'll see many with 6 foot tanks with 4 or 5 foot fixtures.
