A couple days ago my tank went into craze mode..two dead silver dollars and two dead pictus cats...I did water change then Prime..My pleco 6 inches..Jaguar cichlid 2 inches..2 firemouths 2 inches and convict 2 inches are alive...yet the firemouth has a bump on face so I am treating the tank with melafix..Should i leave the two cardon cartidges in the filter? I have the Emperor 400...also my readings after testing just now was 0ppm ammonia...0ppm nitrite...and 5ppm nitrate
