Yes, I have sponges in my overflow and bioballs which i know build up nitrates over time. I also do not have a skimmer
which I know I really need! I"m really going to try and do a few large water changes and rinse a portion of the bioballs off in SW
each week and see what happens. I do run a good amount of carbon/chemi-pure to help with doc
's but I think the main problem is excess meaty foods that isn't eaten by the fish.
I don't get these fish, they don't eat entire pieces of food. I tear up little frozen cubes and they will eat it then spit some out and they never go after little pieces. My clown trigger never seems to each much even thought I've tried like 10 kinds of meaty foods, and my porcupine puffer will only eat krill.
