Will something as simple as this work? I have a 22" tall tank. 1 inch PVC pipe with airstone running from the bottom. Insert a submersible bright white LED tube into the pvc pipe. Algae grow inside the pvc pipe and 1 inch pvc pipe won't look so ugly inside the tank. Is it too small to be any use? Thanks
What light are you wanting to submerse? It'll need to be a warm light (lots of red) for half decent growth. It's also possible that the light is too bright as it's so close to the screen, can you dim it if needed? It'd be fairly difficult to clean, but in theory it should work. I think it's much better to build a waterfall scrubber if you can. If not, a standard upflow scrubber would be better IMO.
Thank you, It is for freshwater. Looks like too bright will be the issue. I'll work on the standard upflow.
