i assummed thats what it was sposed to be doing ( bubbles rising to the surface)
i have a bubble count of about 40 per min, i wonder if they are serving any purpose at all then,been set up about 3 days so i havent really seem any results yet.
bit more info would be fab, im sure going_all_out would agree
well my concern was that they werent dislovling. because the bubbles were almost the same size when they left the counter. but good news is that bubbles are now tiny compared to what they were when they go in the ladder.
