What are you running right now for settings and what size tank? You could maybe take those settings and modify slightly to tone down the power. I dont have par number but It’ll easily bleach sps if you don’t work into it.
It is about 120 par at the sandbed without the (2) T5’s. I am going to take reedings now that I have the new Apogee which reads LED’s correctly. I will post levels with and without T5’s when I get this done
