Thanks,yours is too.I've been using Iwasaki6.5k's.I've used them in the past before but i've only had it running since Dec-Jan when my old tank was stripped of all its LR in preperation for my new tank.It was a long ordeal and many SPS browned out,had tissue thinning(dont know the correct term),and some even lost tissue.The only 2 Acro's that weren't affected during the process were my 2 Bali aquacultured.
