Your opinions on this Ballast please. M59 400w MH (got it on ebay for 100 bucks with a bulb, mogul socket, reflector & shipping)
I plan on making a canopy for my 60g tank that will have this 400w MH setup and supplemental 8 x 30w 6500k screw-in PC bulbs. Can there be too much light? I was worried that the 400w MH might be too much, but it is all I have to work with.
Any suggestions will help.
