Not sure if you’re still having cyano issues or not? But to follow up on my recommendation of TM nitribiotic here’s my results. Nothing changed in tank otherwise.
July 5th. Constant dirty glass and cyano all over the sand bed. 1-2 doses of TM nitribiotic performed so far. It was way worse than this photo prior. I dose it in front of left front powerhead
Just got back from vacation 9-10 days away. Glass was spotless minus a ton of coralline so razor scraped clean the glass.
First morning light.

That was last weekend and it’s even better now. I’m sold! 100% believer in it. Curious if you or anyone else with cyano, Dino’s, dirty glass, etc would see the same results? I hadn’t seen the sand bed in over a year/ever really until now
