Thanks for all the thoughts - I have learned so much from Cory's videos and this forum. I am at a loss but am doing my best to care for the fish until this balances out as I have checked/done everything mentioned (as I have learned).
29 gal tall with some live plants (all healthy and showing new growth). 2 glass fish, 3 serpae, 2 priscilla x-ray, 5 zebra danios, 2 otos, 1 amano shrimp (bought as glass) and 2 glass shrimp - no snails, no dead stuff (looked).
Set up last January fishless and added fish starting in June - Danios and 2 otos in December (1 of each died and removed)
Source water verified before changes - test kit checked with new test kit
My water did seem a little less green(I use a white bucket) with change yesterday, but haven't changed anything to change it. Started with beneficial bacteria when water change wasn't efffective. and added extra Prime to tank, use it with water changes.
Parameters have been:
temp76
ph 7.6
Ammonia 0.5-1
Nitrites 0
Nitrates 40+
I use easy green once a week with leaf zone every other week, root tabs about every 3 since everything is growing.
The only thing new is I put stress coat in with new fish and again when one of my danios scraped itself last week.
