I am with you also in this fight, I just diagnosed one of my systems to have Dinos, I did the coffee filter test. I started yesterday, I purchased equal to Microbacter 7 and read article to raise my temps from 77-78F to 81-82F so I am up to 82 degrees. You can read about it on the forums and youtube, I read a lot before I pulled the trigger.
What I have noticed and this is my opinion, is that my dinos exploded in the increase of the temp and the Micro-bacter 7, I feel it's metabolism is running higher in the warmer water and it will exhaust what ever it is taking on in my tank.
I will let you know as I progress to day #3.
Have you done the microscope ID?
I have posted 3 videos of hoping someone can ID the Dino I have.
