I would like to say first to Jason that I didn't mean to appear to be rude as there is always a chance that there's something going on that we don't fully understand I just think that given the fact that the Bio-Actice CYA reducer was added its most likely to be the cause.
No, no convenient way to check for bacteria. You would need to take sampLes to a lab that can swab agar plates, incubate them and the check for Colony forming units (CFU) after incubation. And I think there's a high probability that you could take samples without bacteria even when bacteria is present and get a false negative.
Thinking about it more I think I would raise your FC/CYA to 4ppm/40ppm and see where it goes before super chlorinating. Given that you've had CYA issues I would be inclined to bring your CYA up to 30ppm with cyanuric acid, PoolMath says that's 108oz. I'd get your FC up to 4ppm and do your best to maintain it there. Keep checking you CYA and hope it stays close or at 30ppm. If it keeps dropping then it's time to super chlorinate. And since you've had a CYA problem I would stay clear of the pucks.
