I read that in the "other magazine" not to long ago...I think we have to keep in mind is that the air pump we use is to pump the surrounding air around it into the pond...If the air pump is around something that emits dangerous fumes 100% of the time those fumes will be pumped in the pond. So, unless you have the budge to pump pure oxygen into the pond I suggest finding a place that is safe and open to fresh out door air...
