Just thought I'd warn you that if you have thicker glass on your tank, don't buy the newest jebao pumps. The magnets are not strong enough to hold the pumps in place -- it slowly slips down the glass. The only way to make them work on my tank is to attach them to my two overflows. Thought I'd give you a warning.
