My apologies for not saying "welcome!", John!


In a cycled tank, nitrAtes should be around 10 ppm. Weekly water changes (25%) and gravel cleanings (25%) help to keep this there. As well, as was mentioned, you shouldn't ever need to completely change the floss -- if it gets really gunky (ie. blocking filter flow) you can rinse it out in some tank water/conditioned water.

Have you done a check for velvet?
