Thoughts on SPS polyp extension..

[Haloreef]

I had massive extention in most of my Sps colonies for a long time and then they just stopped! I tried every thing and finaly narrowed it down to a small voltage leak. I spent 14 bucks on a Rid Volt and within hours the extention was back!
It could be different problem for you but only $14 dollars out of pocket to try.
