Simply attach airline tubing to air stone inlet and place it in the desired location. Size : 8.25 cm (3.25 in)
I purchased 2 of these lights to go on a 40 long tank and I like the look of the lights sitting above overhead the tank.
Of course they have 2 settings one which is a soft blue for evening.
The quality and price have pleased me too.
