Tiny Bubbles

Hi to all - along with hopefully solvong refugium lighting problems, i can't seem to get rid of a proliferation of tiny air bubbles that cover whatever plant life that i put into my ruf. This air is caused by water cascading down from my aquarium above. I have the smallest micron sock on the water input into my ref. which still allows/creates the tiny bubbles. My guess is that these bubbles prevent full water contact away from my plants preventing full water contact, retarding/preventing plant growth. Any suggeastions on how to get rid of these bubbles. My ref. is a standard commercial 15g with all standard compartments. need help- Thankx wilrod99

 

What you say may be true, but also take into consideration that the plant produce O2 which could be forming on the plants.
