Thanks for going to all that trouble. Appreciate that. On a side note, my gripe with juwel is that on their duel strip lighting units you have to have both tubes turned on, or nothing, and sometimes late evening, I like to turn one tube off, which I think is nice for the fish as well. That's a bummer juwel did that. I'd have to wrap something around one tube and not sure that's safe.From my perspective they seem to be a pretty reasonable configuration unless you are an expert and know exactly what you want.
