There a few people I know who have bombed their systems with Bayer. Those who have done it have resorted to those extreme means because they are typically battling regenerations of flatworms, red, black bugs, etc and are constantly losing corals; so they dose the system with Bayer because it is that how much worse can it get scenario vs. a reboot which they are unwilling to go through. If you’re not actually losing corals I don’t see the reason to go so extreme so quickly. I’d go different routes first and identify the issue. Potassium chloride baths are a great indicator for potential pests, bugs.
