Need more light, which one?

125mph · Jul 1, 2024

I have a reef savvy 64x28x22” 180g tank. I want to run sps dominate with some lps at bottom/sand.

I have two neptune sky on the ends and a kessil a360x in the middle. I measured par for the first timr and i was shocked to find out the kessils are pretty weak compared to the neptunes. Even if i crank to 100%, seems like the max it will get is around 250 par at the top rock work. Maybe that will still work..

But im considering replacing the a360x with a kessil a500x or an Ecotech XR15 G6 blue. Which would be a better for the middle/center portion? Or are the a360x enough? Maybe the new a360xe which is suppose to hey 15% more light?

what's your goal? It looks like the kessil is situated between the two rock piles and not above them, so it doesn't surprise me that you aren't getting much PAR from the kessil on the rocks. If your goal is added PAR & shimmer, you could consider the Kessil AP9x, as the optics are designed for a rectangular spread, which will help more power reach the rocks off to the sides. If you just want the shimmer with nominal PAR added, you could even just go with a couple kessil A80s spread across the top.
