Wolfgang,

How are you cycling; with or without fish? Without knowing, my first guess would be fishless and that if you are using ammonia it is the regular household ammonia with surfactants/soap and that is what's causing the bubbles. Do they pop easily and on their own (thin bubbles) or do the bubbles linger (thick bubble)? Is there any type of film on the top of your water?

Sorry I don't have an answer, but these questions will help narrow the cause of the problem.
