Phosphate this morning was down to 0.05ppm, so the GFO is working. I started having some cyano problems on the sand a couple of weeks ago and now can see it on the rocks and glass. It started when I started increasing the light, which the corals like, but which the cyano seems to like too. I have steady 0 nitrate, but steady phosphate problems, so that combined with the cyano is asserted by folks to be caused by biopellets. I took 2/3 of them offline and am trying to run more of the output of the biopellet reactor through my skimmer instead of diverting it to the upper sump in a bypass hose. We'll see if it cures the cyano at all. I'll give it a few weeks.

I also have some aiptasia in the tank. I mixed up some kalk paste and squirted it into the aiptasia as best I could. It kind of went all over the tank, but it should dissolve and raise the kh a bit, I guess.
