If I were to dose bacteria back into my system? What product would you recommend in my case?Given that most of your nuisance is not dinos - majority is cyano - and you have plenty of diatoms too, I'd say you've gotten some good advice from @Lasse and others thus far in the thread. patience, dose to alleviate low nutrient conditions, and manual removal. Together it'll gradually shift things to the good, regardless of which exact nuisance is the primary concern.
