I'd consider switching to vinegar or vodka, and ramping up the carbon dosing. The Bio Fuel should be fine, although it might be pricy. That's a lot of food going into the system. I might cut back on that.

What about suger and what is the dosage would greatly appreciate some input

Sugar is another form of carbon dosing, and it seems to have a higher probability of bad side effects, so I personally wouldn't use it. It might work, though. We don't have much high-quality data on the various forms of carbon that get used in our systems.

Thanks for the info think I'll try 5% vinegar, what do you think as a starting dose I've read 15ml per 100gals to start dosing before or after lights go on

I dont think carbon dosing is going to help reduce these cyanobacteria. What i would do is check my NP ratio and dose more bacteria. I personally would use Microbelift special blend.

Well after trying carbon dosing for 3 weeks the cyno started getting on the rock work and creeping on my $ 390 scoly so i pulled the trigger and dosed the tank with chemi clean and after 48 hours i never saw my tank so pristine and all the inhabitants are all doing well , so for the time all is right with the reef Gods
