I'm not trying to deflect but am I supposed to have literally NO algae in the tank? What are the fish supposed to graze on, besides supplement with Nori?
Its a refugium grow light...not just some random red light bulb. I don't have the specs on it though, but its small enough to fit into a take out container. I've been running it 24/7. Perhaps I do need a bigger brighter light, but I had all the parts already and putting it all together was a spontaneous idea literally meant to just be an experiment, until I noticed the hairy GHA slowly going away, and I thought I was on to something.
I still see it as a success and and I will continue to use it, or put together a bigger, brighter one.
I stand corrected on some of my comments on this thread, but I remain convinced that the thing works very well.
Thanks to
@VintageReefer for showing us how well an ATS is supposed to really work!
