No polyp extensions? I was a fan of stuff like "liquid gold" to promote coral growth, but I have come around over the years to agree with the majority, that if you can't test for it, don't add it. There are too many tanks out there full of
SPS coral that don't use all the fancy additives. Flow, salinity, alkalinity, calcium, temperature, PH, proper lighting and zero organics grow coral. I don't think you can subtract any of those things and be successful long term.
I hit the calcium hard with B-Ionic AND Kalkwasser additions. I also use a reef salt high in calcium. For me, that has set the
LPS and
SPS corals into growth mode.
