ok, I recently got a new a new cartridge for this little undergravle filter that I have in one of my bowls, and even though I rinsed the darn thing for like 20 minutes under running water, it still clouded the water when i put it in the bowl. After I took it out and changed the water, I noticed it had stained my butterfly's fins like a dark grey it has been almost two weeks since then and it seems,if anything like it is worse. So............ how DO you get a stain out of a betta??
