The acros aren't browning anymore <3 Everything looks good aside from the cyano mess. I wonder if I can use that little reactor for biopellets or somesuch?
Glad everything is looking good. Sometimes I think cyano just has to run its course. I have it in the seahorse tank but not in the LPS tank. Both tanks have the same water and lights but the seahorse tank has only been up less than a year, the LPS tank has been up for 2 years but the rock and sand were transported from a tank from 2004. Keep up good husbandry and perhaps try the pellets or vinegar dosing and you will surely beat it eventually. I wouldn't worry too much about it.
