Hello!
SM: There is no "insert image" button viseble above the text box to me?
Here is my test scrubber as a participant in this test group.
Sceen size total: 11x5,5 inches
Screen size effektive: 10x4 inches
Light: CFL 18W PL-L 2700K
Air stone: 4 inches
Thing i have to change: Have to cover up the screen back side to block the light getting trough to the aquarium, fish and corals have now 24 hours of daylight
Question: The screen is probably way to big, but i figured i could use height of the aquarium glass. Is this a problem should i make the screen smaller for this testing to be right???
