Aquarium Advice Addict
I would either put a raw shrimp in and let it decompose or does with PURE ammonia. I did the ammonia route. If it has cycled you will see ammonia spike and start coming down while nitrite rises. Next the nitrite will start coming down while nitrate starts to climb. Once ammonia and nitrite are at 0 do PWCs until nitrate is below 10 or better yet bellow 5.
