Just joined so hi all.
Here ive made a Hotizontal Scrubber that fits on top of my sump, hooking on to the glass devides. At the moment its got 12 Cree leds. half cool white and half 3000k warm white.
I made it because my chaeto was getting covered with cyano and dying. Ive got green hair in the tank, but the scrubber seems to have seen the cyano off.
Just wondered what you all think / would change.
