I thought micro bubbles were bad now I have micro micro bubbles which are worse because it doesnt look like bubbles it just looks like your water isnt clear and its stiring up sand particles...but its not. Well it seems that most of these bubbles are coming from the overflow...i tired baffles well an attempt at baffles and it didnt do so well. Now i really dont wanna have to redo my sump again so any suggestions?
