Thinking I have an outbreak of cyano. I have a reddish brown algae covering the sand, and I’m having to scrape the glass multiple times a day and it’s making the water cloudy. Any recommendations? Not sure if this related, but I had bottomed out nitrates few weeks ago. I increased my feedings to twice a day, but this cyano seems to have gotten worse. I’ve been dosing NeoNitro and got my nitrates to 4 so I’m happy with that. Nothing appearing stressed. I’ve stopped dosing coral animos daily, and temporarily stopping feeding the corals incase this is fueled from a nutrient overload. My parameters have been decent other than my low nitrates. I’ve added more snails over the weekend too. Trying to combat this as naturally as possible.

12 days away, fed an appropriate amount of pellets every day and nori every 3-4 days. Phosphate 0.08, nitrate 0 (locked up in algae I’m guessing), alk 6.8. Scraping produced full sheets of algae which I tried to scoop out but the reef mat did 1.6m the day I cleaned it. I also have an INKBIRD and WiFi control of the ac. Final photo is after 20L water change. I’ll do another in two days to lower phosphate and raise alk slowly (coral pro salt will rapidly raise alk if I go any quicker). In future, I’d put a fan on the ‘chiller’ outlet for the INKBIRD and sit it to blow over the sump. Fish and inverts fine, green torch is only half extended (phosphate?), maybe some others have less colour but the alveo is the happiest I’ve ever seen it.

So I tested parameters today. All looks okay. Nitrates are a little high but nothing concerning (I wouldn’t think). The only thing I see is calcium being pretty high. Anyone have any ideas why I might’ve had the cyano outbreak? I’m trying to make sure once the lights come back on that it doesn’t come back swinging, but I can’t seem to find the root of it. It could just be me not looking in the right place, but hence the questioning.
