My tank is a Nuvo ext Mini. Right now I mostly have Zoas, but they seem to be stretching. I'm running a Maxspect Ethereal. Concerned with the Zoas, I rented a par meter from my LFS to see how much light is actually getting to the bottom of the tank. What I found was a par of about 50 at the sand. I even cranked the Ethereal up to 100 at across the spectrum, and I didn't get much better.
My question is, is this just what I can expect to get out of the Ethereal, or am I better off running say, two AI Primes?
