Sponge Filter

[Jack1235]

Can you use sponge filter and air stones for saltwater aquariums

 

[dakoop]

Can you or should you? There are much better ways to run saltwater tanks. Why would you want to use air stone and sponges?

Salt creep would be a major issue.
What's the thoughts behind using a sponge?
If it's oxygenation, point a powerhead at water surface.
Skimmer should keep system sufficiently oxygenated anyway
