Been having problems with Cyanobacteria. My tank was looking horrible yesterday morning. Sand all red, lots of red spots of rocks. Added 1.7cc of Nualgi at about 4:30 when the mail came. Left on LED lights on so that I would get more than the 4 hours of lighting to start the Diatom growth, was up in the middle of the night to turn the lights off (so I wouldn’t burn any corrals) and the cyano is gone from the display tank. I didn’t check the refugium yet, but amazed. I didn’t get as good a result when I recently used Chemi-clean. Photos soon.
Awesome!, Richard. Glad to see Cyano disappear overnight!
If you have read posts from other trialists, you will have noted some have had more algae after dosing Nualgi. That is because Nualgi purges the sand and rocks for nutrients. So you may still see that if you do have nutrients locked up in those areas. In weeks 2-4 nualgi will starve those algae too…if it shows up, you will need to stay patient! Keep in touch….you can leave the UV in or out – does’nt matter to Nualgi dosing
