Long story short as I can. I've just noticed my filter isn't working. I've switched an airstone on and hope it helps some. I have a new rio that hasn't been used yet. I've put sand in and that's all. Can I put the filter sponges from my dead Fluval 2 into my rio filter and fill it up and transfer? If so, does it matter where in the rio filter I put them? Please help!
