I waz wondering if its a good idea to run air through an airstone into the water? In the sump. Reason im asking is because i have read that the oxygen levels in a sw tank doesnt have very much O2. Does anyone use them and if so, do you notice a difference? What kind of stone do you use? I mean, we use them in the buckets while mixing the water, why not leave one going in the sump?
