lights but everything shriveled up big time, too much light or the switching of bulbs?
There was more flow in the nano...I had an extra pump giving out additional flow and that was in a 12 gallon. Think I need something more on the biocube?
Nope, wasn't saying the 20,000K was a bad idea, just pointing out that it is going to change the color spectrum and make things look more blue. The shriveling is probably a combination of both factors. As Doug pointed out, water clarity can also play a roll, so if the the corals under strong MH
lighing were moved into your tank with less light, they may be closed up do to drop in lighting - this would be perfectly fine, as they will eventually open up as they get used to the lower lighting.
Personally, I've found flow rates to be a big issue with zoas in particular, so you may want to look at adding some addition powerheads in order to increase your flow rate and see if that helps the zoas open up.
