I am getting back into the Hobby and I have found that many have done away with VHO and besides they are dang expensive now.( Of which I can not believe lol. ) But I have a pair of 4OO Watt electronic ballasts and 2 brand new 400 Watt XM 20K Bulbs.

So before I build the hanging canopy for these lights are they too much or would I be better of to trade them to someone that needs 400 Watts for a pair of 250's?

The Tank is an Oceanic 125 Gal 6 foot long and 24 tall.

Thank You for any help.
