View Full Version : Sponge filter

How in the blazes can I keep the stupid filter from floating everytime I change the water in my discus grow out tank? I keep having to squeeze the bubbles out...

You gota keep it under water or it sucks up air I have the same problem some times.

You can get sponge filters with a weighted base. Can always glue a small piece of tile to the base to weigh it down.

Squeeze the air out of the sponge underwater. That eliminates a lot of the buoyancy.

Like Jim says you have to squeeze all the bubbles out underwater but it isn't unusual for me to have to do this repeatedly for a couple of days with a brand new sponge.
