Sounds great Brian.

Do you think the LED lights add anything to the green water production?, or is the spectrum just not there? Just never looked that close at LED other than for control stuff.

I have some 6500K 99.8% spectrum fluorescent lights left over from the Florida Building (that was at my shop), those should work pretty good. Also have some 2' fixtures with similar bulbs that I use in my mini green house.

Maybe I'll give the green water a whirl in one of my 40G breeder tanks. Like you say, the learning curve is up there, and I'll need GW for future plans.

Thanks!!!
