Yep, poor nutrition causes ammonia to be released into the water column. It is highly unlikely that you would have wiped out your filter bacteria just by not adding de-chlorinator. This product is added to protect fish, not bacteria.PM said:Well I thought you said that ammonia causes algae? ie, I wiped out my filter bacteria by accident, resulting in GW.
If CO2, dosing and circulation are OK then O2 is produced properly and is also OK.PM said:I refuse the idea that I have poor circulation, CO2 or dosing, maybe poor O2 though.- ten times filtration, all areas of tank have visible flow, and healthy plants.
It's likely that your green water occurred as a result of too much light for your level of dosing/CO2. Adding more light when you have algae or poor growth is usually an invitation to more problems.
