I got a green slimer acro yesterday and had it on the frag rack for a day which had great polyp extension. I glued it to the rock today now I'm not getting any polyp extension. All parameters are good alkalinity is 12 calcium is 470 magnesium is 1350 no3 is 5ppm and phosphates is .05ppm. It is getting great flow with the sicce xstream sdc. All other acros and sps are doing fine with great polyp extension.
