Default Thoughts on SPS polyp extension..
What causes polyp extension in SPS, or rather, what causes polyp retraction? I noticed a few months ago that about half my colonies no longer have noticeable extension, day or night. Others are fine, although not what they once were.
I think it started with a change in salt, but returning to my original salt hasn't restored the PE...

Thoughts??
