So I've noticed that my water isn't as clear as it used to be. I wouldn't call it cloudy, I'd say I can see millions of tiny bubbles everywhere. I don't know what is causing it. I thought it was the sponge that's on my pump sending it back into the tank. Should I take the sponge off, or do I need to have that on there?


Anyone have any ideas?


Thanks,
