Coop sponge filters

[Nana Finopolis]

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.

I think that would have the same effect of making the filter shorter and the uplift tube longer.  I suspect there's an underlying issue.

Could you take a picture of the problem and how your filter is assembled (maybe one without the sponge so we can see the tube routing etc)

 

If you want to prototype your idea you could wrap that area in saranwrap and see how well it works.

Thanks for responding. Here's a link to a short video without the sponge. I also included a picture here.

Huh.  Looks setup okay to me but I'm not an expert on setting these up as I only have one.  You could try adding a bit of line to lower the airstone which may help them "gain inertia " before they have to get restricted at the top.

Thanks CT, I've tried different lengths of tubing. I have about 5 different lengths cut, lol. I appreciate you trying to help though.

Thats what I do
