Hi I have a 3x2x2 tank and 15"x34"x10" sump. I currently have a 13"x6" screen.
Firstly is this size correct? If not, what size do I need please?
I am running cfl bulbs the 23w 27k and 2 on each side. I'm looking to switch to led and have been told to go to red LEDs as this is the only colour that produces a lot of algae with no yellow strips. Can anyone point me in the direction of buying the red LEDs please? Thank you
