I might consider a swap to the Hydra but I'm not sure how much better the spread would be on my little tank; it still just has 2 pucks that are quite close together. I assume that it is effectively just 2 Primes in one fixture?
What I think I need is a 'panel' but most of the top brand units seem to have the LEDs packed fairly close together. Something like the Reefbreeders LEDs might be better for me.
Radion XR30 might work (I assume I'd have the same spread issue with the XR15) but it's significantly more expensive than I wanted to spend on a Nano tank
