The tank I am trying them out on is a 37 gallon, so 30 x 12 x 22ish. I am aiming for a cost effective way to get medium/low light. I don't want CO2/high light.
With the 2 colormax and 1 white it seems to work well. Some may prefer what Aqueon recommends of the 2 white, 1 colormax.
I may go that route for the 46 gallon 36" setup.
I do wish the bulbs went to the end and weren't just 24"s.
I would have went with the buildmyleds but at double the cost, then having to add a dimmer seems a bit silly. Sure I could someday switch it to a high light/CO2 setup if I wanted but I highly doubt I will ever want to go that route.
