Crazy-sps, yes it's Brian and I only saw his tank once, a long time before he worked at MSM, and it looked fine except that he had been experimenting with mercury vapor lighting and I didn't like the look of it. Did you ever see his tank?
Thanks for the compliments about the tank. I wasn't sure about whether you had noticed the three SPS. I mentioned the frogspawn because I was totally amazed at how two of the three frags were the tiniest buds from Steve Lopez that we didn't know would expand so large, like 30X the size of the skeleton!
From what I've seen, the systems that have the best growth of SPS must have MH lighting, skimming, furious upper water movement, and a calcium reactor. This seems to be the best environment for clams as well. After those four aspects are met, everything else is negotiable.
If I recall correctly, Fluoride was discussed in previous posts as no worry.
Jon, Perhaps there are some who wish that were true
