mcarroll Posted September 5, 2019 Share Posted September 5, 2019 Looks like cyano or cyano+something co-blooming. Can you take more pics with the flow off? Also try taking a sample with a little tank water and shaking it to break up the algae. Then let the sample sit in light for a while to see if any of it reconstitutes or moves at all....the "good ones" won't move at all. If it moves, there are dino's in it. Can you tell us a little about the tank and how it was started? Do you have test results for nitrates and phosphates? Quote Link to comment
