I began this hobby with a RSM130, that was a good tank. I got addicted and upgraded to a 150g mixed reef tank in about 2yrs. So I've done both, the all in one and custom route. Right now, space is an issue so I decided the RSM 170 is about the size I can fit. I plan to start with some LPS, wondering what others experience are with this tank. Would love to see any members 170's
