I think I have beat it it was dinos I left the White lights off for most of the day and had the blue light on for most of the day and it seems to have gone I also bought some caleupra just incase I have any toxic chemicals in my water and to feed my tang because he doesn't eat sheet algae weird
Probably diatoms, dinos are much harder to beat than just that. Dinos isnt an algae, its a plankton but they look like algae. Just like cyano is a bacteria but looks like an algae etc.
Sadly it came back so I got very angry so I thought sand sifting goby so I bought myself a dragon goby lol and it started when I put it in so these are the best cleanup crew ever
