you've inspired me to do my own horizontal algae scrubber. installed it with a suction cup onto one of my sump partitions. Literally took me 3 minutes to install, the hardest part was roughing up the surface of the screen.
I have a bunch if 50w led
flood lights that I ordered a while back off eBay, these things put out a lot of light and are virtually waterproof, so I hung one from my skimmer outlet pipe going into my sump, it hangs about 2" from the scrubber screen.
I get about 6000 gph
of flow over the screen and all my tank water flows over it.
What do you guys think?
hoping to see some growth in a few days!!!
