Just replaced my Reefbreeder photon’s after 6 years with the Photon V2+. One side was flickering to a lower power so I had to make the switch. I am hopeful that my SPS will start coloring up with this new light. I also broke down my bio-reactor and cleaned all the parts, so should should see a little lower nutrients. On a side note how long does it take for the base of SPS colonies to regain color?
