Bubbling nutrient problem`

17 years ago

I'm using an airstone in my nutrient solution and bubbles are forming a foam at the nutrient surface which is pushing the seedlings up through the holes.

I have done some searches but it seems this is not a common problem - can anyone tell me what might be the possible causes of this bubbling and how to eliminate it?

This is my first try at Hydroponics and am using floating styrofoam in a plastic container which holds the nutrient solution.

Thanks
