I have a HOB refugium I’m planning to hook up on the back of my tank and I’m looking for a good light to grow some cheto algae in it. I can find some led, that hang over it, but a long time ago I saw a video where someone set up a submersible grow light that his cheto grew around. Wondering if anyone has any recommendations for a specific light or insight on the subject as my online research has come up with nothing. Any help is appreciated.
