My media is setup EXACTLY as shown on Eheim's site except for my addition of floss on top of the white pad. For a setup that hasn't the remotest chance of working and a decimated bio colony ( your words ) my free ammonia level miraculously reads 0.001! Once again I will state I DO NOT do monthly cleans. If you think I am doing something wrong then my wrong ways are achieving fantastic results of 0.001 free ammonia levels. Levels that everyone strives for.
