Salty Rambler November 25, 2023 Share November 25, 2023 From the one pic, it looks like it may be cyanobacteria. Does it blow away easily when disturbed? If it is cyano, manual removal, water changes, good flow, and making sure your water parameters are in range can help. Link to comment Share on other sites More sharing options...
Origami December 15, 2023 Share December 15, 2023 Confirm it looks like cyanobacteria. Is it less obvious just before lights turn on in the morning? Cyano can photosynthesize, so it tends to get worse as the day progresses. Sent from my Note 10+5g using Tapatalk Link to comment Share on other sites More sharing options...
