Nitrate control options..

That amount of phosphate and nitrate is fine for macroalgae to thrive.

Thank you! I also read your article a brillant read! some of the science went over my head though lol

Flow gets a laser-focus in algae scrubbers but is rarely mentioned in context of chaeto. (Tumbling sometimes is the stand -in)
I think its important here too. It was in my tank.

I had Chaeto die on me 3 times! Drove me nuts. I bumped up my P04 and added Iron and it was off to the races. I fought my nitrates also as they were hovering around 20 with no relief in site. So, I added a bio pellet reactor and they have dropped to 5! I used about half the suggested dosage and have seen no negatives. Oh...my light is a Kessil H380 for the fuge.
