Purple Tang HLLE

[painter1982]

I’ve been using ozone. No carbon ever. Parameters all good. Low phosphate and nitrate. I dose AFR. My biota yellow tang is getting HLLE. I can’t get it to eat anything but the 5 different macro algae’s I have and whatever grows on the rocks. I don’t know what else to do. I’m going to stop the ozone.

It doesn’t eat mysis?

No. It’ll look at them and turn away. It always stuffed with algae. It’ll eat other fishes turds though.

It’s probably quite full. As long as it’s fat I wouldn’t worry

It’s one of the suspected causes

Proper ozone use has been ruled out as a contributor to HLLE (by the huge number of public aquariums that use it). I can't speak to chronic overdose applications of ozone, but acute instances of high ozone don't seem to cause it either.
