Hello everyone i just recently acquired this motoro stingray and iv done some research and im not sure if he is healthy. I just put him in the tank yesterday and he ate right away but he was "breathing" heavily. Iv been having an issue with high nitrates and iv been doing 50% waterchanges 2 times a week to keep nitrates under 40ppm. I have a 100g tank with 2 cascade 1000 canisters each rated for 100g. I have 3 florida gars,3 peocockbass,2bichirs ,1 motoro in the tank(yes i know its overstocked ,im sorry). I have plans for a 300g and i also wanna try and sell or possibly give away 2 bass and maybe 1 gar. So i tested my water and my nitrates where above 40ppm and my ammonia(which iv never had detectable levels) was around .25ppm i went ahead and added some prime and right after work i will do another 50% water change. My question is how can my ammonia be detectable with my nitrates being high? Also i ordered some more bio media for my canisters and i was wondering is more bio media will raise my nitrates to deadly levels.
I have had this tank up and running for over a year now
Please any help will be appreciated
