I added the little bacteria balls about a month ago when I upgraded from 10 gallons to 36. I amHave you tested the ammonia in your tap-water? Are you using a bucket or a hose that's contaminated with cleaning chemicals?
I doubt it is caused by the live plants unless they are dead and rotting, removing them means that they are now not removing ammonia.
Logically the water change should have changed the ammonia to 4ppm, that is why I ask about testing the tap-water. An oily film suggests something has contaminated the water, we all probably see an oily film if we have overfed a fatty food. That is why I wondered in earlier post if someone might have tipped a half pot of flakes in tank. But now I am worried the contaminant is something in the tap-water, though I am sure you have noticed if something oily is in your tap-water.
Did you add a bottle of Dr. Tim's ammonium chloride mistakenly thinking it was bottled bacteria?
Using tap water which is not oily. I put water in buckets and added API tap water conditioner and Prime Seachem concentrated conditioner. It’s what I’ve always added when doing water change. No other changes have been made. Feeding small amounts which they all consume within a minute. Ammonia has never been over 1.0 which then went down to .50 in the last week. I have been working on lowering that as I understand the cycle isn’t complete. I’ve posted pics of all I tested. All I added to bucket water. Also added ammolock after first water change today. I’m going to test my tap water ammonia level now. View pics pls
