I tried counting it seems they have 12. I know they don't but there so small some seem to have more and some seem to have less then 12. More importantly now I had another ammonia spike at .75-1. I did a water change and added prime and stability and will do another water change tomorrow. I still have no idea where the spikes are coming from. I have the chemi-pure elite in the tank but is there anything else that would remove the ammonia in till I can find the source. I know there are ammonia removers you can add but I have read most of them do not work.
