I haven't seen polyp extension on any of my SPS except an orange digi and a BOP birdsnest. I did a 2 gallon water change just now... Its like a miracle or something! It turns out SPS corals like their water being changed! I'm starting to think they like clean water! lol. My ORA German Blue Digitata already has its browned out polyps(from not being out?), with a little bit of blue color left, coming out! Also my acroporas have a little bit of polyps come out that didn't even come out on the mother colony I got them from. My green acro also has poylps coming out which I'm happy about. Thanks for all the help. I'm also going to do another 2 gallon water change on friday.
