"I have a 120 4x2x2 with a center brace like yours and I am using 2 AI SOL Blue. It looks fine. I have it 12 inches above the water. This is what the AI recommends! "
I bought these with the intention of upgrading my 39G, and haven't had the time or $$ to do so. So I'm passing on a good deal, these were $880 ($399x2, and $80).
Think they would but would need to get them about 12 to 14 in from water surface on your 120 24x48 Craig has 3 on a 180 24x72and there at least a foot off water surface!
