View Full Version : 1000W is too much right?

I have a client that has a bunch of metal halide setups that he's not using and he said he has 400W and 1000W.
I don't have any experience with MH yet so just checking here to see if 1000W is too much. I was looking to do a species specific tank with these lights, but I don't have any particular corals (or clams perhaps?) in mind.

well, if you can afford 1000w+/h, have a goodsize tank, cooling system, the home ac capacity and are looking to keep sps, then 1000w can be great... (I wish I could do 1000w) if you want to keep softies then you really do not need the power. 1000w with steady water parameters and correct calcuim levels can yeild great growth for certain stony corals

If I were you I would go with the 400 over the 1,000...especially if you've never played with halides before. Big lighting gets HOT and needs to be managed. You can easily cook at tank with 400's, let alone 1,000's. 400's will provide plenty of PAR for nearly any coral you are likely to find and too much for many.

Not needed! It would be cheaper just to buy a set of lights than running those. You'll need a chiller for sure. The cost of electric will pay for them in about a year.

Pick up some good reflectors and you won't need that much power.
