70w MH on a 2 gallon?

[Cosmo^Kramer]

Does anyone think a 70w MH would be too much for a 2 gallon? I'll be stocking small LPS and a monti digi or two.

The only thing you'd probably need to worry about is temperature and acclimation. With only 2 gallons, it would be very easy for the MH to heat up your water to inhabitable temperatures. In addition, any new coral additions may not be used to being placed so close to the lighting, so proper lighting acclimation may be needed.

As long as both are covered, there would probably be no reason why you can't keep 70watts over 2 gallons, although keeping temperature down would probably be the most difficult part. Raising the lighting or using fans should do the trick, but you may inevitably have to use a chiller to keep the temps down.

70watt MH over a 2 gallon cube, probably one of the most beautiful and unique tanks I've ever seen ^_^

i can work but i might invest in a nano chiller to go with it
