I have a small 12g nanocube and was recently given some SPS frags. Thanks again Joshua. The stock pump was already upgraded to a Maxi Jet 900 with a hydor flo rotating output. I was under the impression that SPS needed TONS of water flow and I figured that my single pump would not be sufficient. I had an old rio 180 laying around so I tossed it in there blowing directly on the SPS in the back. This was 2 days ago. When I got home today I noticed that one of the frags is looking rough. On the side of two of the branches facing the direct water flow, it has died and is white, while the rest of it still has color. Also, my other soft corals are getting blown around aa ton with the additional powerhead and seem unhappy. Anyway, I removed the second powerhead.

2 questions.

1) Did the powerhead blowing on the SPS kill the coral on that side? That's what it looks like, but I thought lots of flow on them was good.

2) Since my tank doesnt appear to be liking the added flow, do I really need more flow or will I be ok with my single maxi jet 900?

This is my first attempt at SPS, and I am pretty upset that this happened as that was my favorite/largest frag. The rest of that frag still looks fine though, can it regenerate, or is the white part game over?

Thanks.
