Im not understanding how a discussion on the “censored word” ratio will help the OP resolving his current issue with nitrates, I believe there is places on the forum to do that. (Or used to)
Meanwhile, wouldn’t it be more productive and friendly to just try and go back to the focus of the thread? that is the rise in nitrates. Were the OP may require some assistance and option into find solution to lower nitrate without affecting his phosphate as I believe it’s within acceptable range.
The OP literally brought up the Redfield ratio and how fixing that ratio would help/solve their algae issue. That is false and a very poor way to go about fixing the algae issue.
I can’t think of a single scenario where someone solved their algae, dinos, diatoms, cyano, you name it issue by getting nutrients into a certain ratio. Maybe later I will write up my post of why using or chasing a made up ratio is dumb
