If I were to take the algae from a scrubber on another tank and scrape it off into a tropheus tank would they eat it?
I have a 10 watt 660 nm with some 460nm. It is too focused to use in the sump. From what I read.Glad to hear. I was going to say that you need more flow, even for 1-sided, but since it's set up and working you can just keep it as is.
As for lights, maybe you can test some ones that I just made. They are submersible.
And as for upflow, should be simple enough if you have the depth.
