Toadstool and gsp not extending?

[Elo500]

Recently my toadstool and some of my gsp don't extend their polyps as much. The change coincided with new PC bulbs I installed in this 24g nano cube. You can see in the pics the gsp toward the back of the tank is fully out. Could it just be the light? I do water changes every week.

Hi Erich,
In my experience, when my soft corals stop expending their polyps (especially gsp), it's an indication that something is up with my water. In your case, it may very well be your new bulbs, however, a smaller than usual water change wouldn't hurt. You could wait a couple days before changing any water to see if they bounce back with the new bulbs. Keep us posted.

+1 on more water changes. My experience is the same as Matt's.
