I'm going to start up a 40 breeder. I have 2 36" Finnex ALC lights I bought for a freshwater planted tank. It is customizable as far as colors, and has great par levels, especially since the40 is 6" shorter than the tank I had it on (a 65). Seems a shame to spend all the extra cash on new lights when I have these already. Assuming I can customize them to take out the red and maybe the green, any issues with this?
