Hi , I went from cyano to Dino’s and tried various methods including multiple bacteria strains and quit all aminos/ reeef roids no whites you name it and what worked for me was uv-c light I have a 60g I bought a 18w and plumbed it directly to the display with a 180gph pump And within 24 hours 50% was gone and in 3 days not a slime bubble in sight but I believe it does not work with every form of dinoflagellates I guess I was lucky.
