just to make sure...T5 actinics need no special fixture and can be used in a standard T5HO fixture right ???
have 2x 24 watt 10k tubes...
if i change one to actinics, will there be better light penetration or will the soft corals be shocked ??
besides looking more blue/ pleasing to the eye, does it benefit zoas/ mushrooms/ anemone/ coraline ??
