Please help identify this! We just noticed it a few days ago and want to act as quickly as possible if we need to treat! Also, we are definitely losing a battle to what we believe is Cyanobacteria, if you can see it on the rock. Any suggestions on that as well would be super helpful!
Thank you in advance! We’ve had our tank for almost a year now and are so happy to join for discussions/etc!
