I have just upgraded my 75 gal to a 135 gal. Just pickup the tank, stand and canopy today. I am going with a retrofit that has 2 VHO's and 2-250 MH. My question is what does everyone do with there ballasts. I see everyones canopy with retrofit and can't tell where they mount their ballast. Thanks for any help. I am new at retrofits.
