Hi Greg, beyond impressive, congrats! As we all learn by failures, but then a break through to the next plateau occurs. We all know to change things slowly in this hobby, therefore, can you share a few of your early break through experiences with SPS? For example, struggles getting corals to color up? Was it lower phosphates? Dosing expensive trace elements? I just read your TOM thread and noticed your lighting schedule is quite long. Can you give me your thoughts on what you have or would see if your MH's were on only say 5 hours per day and all rest of your lighting is a 10 hour period? Would your SPS brown out? Have you experimented and found a threshold? Thanks for sharing your awesome reef with us ....
