Thanks! I did end up losing most of the zoas. I knew it was a gamble, but sometimes it's interesting to find out how it will go. There are nuclear greens, and purple deaths still surviving.
The goldflake seems to pick at corals the most.
Thanks to my LFS I upgraded the return pump from a Mag 18, to a Red Dragon 8.2. About 200 more GPH and half the wattage. Plus it is so quiet! I didn't think the Mag 18 was loud, until I plumbed in this pump.
Love it. Would love to have a really big tank one of these days.......Biggest one I had was a 150 custom plywood and fiberglas back in the 70's. Technology didn't really exist back then, and we only ran carbon filters and did water changes. Never tried to have anything but a very few fish.
