Noticed this yesterday and today I did a 40% WC as well as a full cleaning of both FX5 filters including adding 3 new outer sponges, a fine filter pad and a new box of media to each of the 2 fx5's I have running. I also added additional aeration as well. What else can I do? All perimeters seem ok. 7.4 PH, 0 ammonia, 0 nitrate, 0 nitrite, 1.0-1.5 phosphate. Any recommendations? Also he has a gash on his face I planned on treating with 35%-40% WC every other day for the next 10 days and possibly some melafix.
