The AquaTop BREZA Sand Airstones are uniquely shaped and boast an incredibly porous surface, which allows for consistent even air distribution. This even air flow creates a beautifully consistent column of bubbles. AquaTop BREZA Sand Airstones provide the oxygen your aquarium fish and plants need for a healthy life. Made from pressed sand, the BREZA airstones allow for uniquely even air distribution in the tank, with a notched shape to increase bubble-producing surface area for maximum aeration.
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.
