Just wandering some things about others and dinos. If you don't mind sharing any info about whether they came and went with a certain level of nitrate and/or urea. For example they got worse after adding fish which would be more fish pee and had zero nitrates. For example started carbon dosing dinos appeared while nitrate suspected to be too low... corals whitened. Also interested if you dosed potassium nitrate or other nitrate and if it killed them.
