im having the most random ammonia spike in my nano 10 gallon, its been setup since beginning of sept 2022, and i added a bubble tip anemone about a week and a half ago its been happy and all has been good until yesterday morning i woke up and it looked as if it had started to melt away and then perked right back up to full size and color by night time, then this morning the same thing has happened i ran tests yesterday at night time and all my levels were 0 ammonia 0 nitrite 20 nitrate ph 8.1 alk 8 its a softie tank so i dont test mag or calcium often so i didnt test that, but i water change once a week. This morning i woke up to do another water change because i tested the tank and its at .5 ammonia but nitrates have dropped down to 5 since doing two 20% water changes. im not over feeding and im doing 20% water changes weekly, the only thing ive added recently was some dry rock to aqua scape a bit better but everything else was here before the nem and all params were fine. is it possible the nem is causing the ammonia spikes? it seems like the ammonia gets high during night and drops to zero by lunch time when it fully reinflates. tank only has two two inch clownfish and a inch long coral beauty baby (doesnt nip or mess with and isnt permanent just is to small to live in my main system) any advice on what i can do or when to pull the nem out?
