siniardem Posted May 27, 2022 Share Posted May 27, 2022 I am sure this has been asked before, but I have been moving and out of the aquarium world for a bit. My small sponge filter is either clogged or something isn't working right. Checked airlines and air pump- used two and still having issues. It seems that the bubbles are only one per second out of the fiter and it is the only thing on that airline. No valve connected to adjust pressure. Noticed this in the last week or so. It is a fluval 2.5g so it has a built in filter but the sponge is better. Just I have a backup. Either way its an aquarium coop brand and i have tried to wash it out. No real debris but some dark moss around the top- thats been there for months. Not sure what to do or check!! I want to keep the blue velvet shrimp going strong. Thanks!
