Nana Finopolis Posted May 5, 2021 Share Posted May 5, 2021 (edited) I'm using these and love the larger pores of the sponge. But, I'm having a heck of a time getting them not to "leak" air bubbles out the side. I've watched Cory's video a couple times. The air pump is turned way down. The tubing with the never clog airstone can't be any shorter. Next, I'm going to try using a short piece of uplift tube to corral the bubbles to send them up instead of out the sides. I don't know if it's even feasible, but, I was thinking if in manufacturing there were a small solid piece where I drew the line if it could help prevent the bubbles escaping. Maybe even making the disk where the ends of the red mark are touching were made a little larger would help. Any other ideas are welcome.
