I have jbj 12 gal nano and have had it going for two months now. I was reading to take out the bio balls and the ceramic rings ....what should I use any suggestions from those with same tank? I have just put in 4 peppermint shrimp, two snails and a damsel.....next week or two will be adding coral. water levels are testing good except for nitrate went to 10. Will do water change and new charcoal. Have sponges in first chamber, ceramic rings and bio balls in second and heater with pump in third.
