In the morning when the tank is all blues from 8a-11am my torches look good, nice and puffy. Then the T5s come on and they shrink up. T5s are on from 11-3 and peak PAR at that torch level in the sand is roughly 200. Once T5s go off they remain small. This is a new issue as of a few weeks ago when it started. In the past the T5s never bothered them.
