I definitely understand your frustration. I'd suggest following vetteguy53801's advice carefully. You've got multiple problems going on with dino and cyano and probably some other stuff. But all or most of them are dependent on light, so cutting light down should help. Run your skimmer to collect soluble waste that will accumulate as things die off. Run a UV if you have one. BTW, what is your source water? Are you using RODI?
