    My eheim pro 2 has crashed for the time being....I don't have anything else to filter it with till I fix it....so how am I supposed to keep this going?? I can add two air stones, and I have an 2 empty (no cartridge) filters on it...but I know this isn't enough...I have 4 angels, 3 kuhli loaches...
