i started dosing calcium and alk because im switching to sps and slowly starting to phase out the softies. i heard its much easier to raise sps specifically rather than a mix. so it could be the dosing doing it.

I've had the same thing happen recently with some of my Rics which were under 250W MH. One colony I had for 4 years and then suddenly they all turned white and disappeared. Around the time it started happening I dont recall doing anything different to my tank. If anything things were improving because I was bringing my nitrate down from ~10ppm to <1ppm with a few improvements to my filtration (larger skimmer and filter socks).
Salinity 1.025 (refractometer) Temp 27ºC pH 7.8-8.1 Ca 400 Alk 10 Mg 1300 Nitrate <1 Phosphate .1 (was higher back then and has always been higher until now)
