Looks good! Just got nearly the same tank from river city a few weeks ago (6'w x 30"d x 25"t) tank from river city a few weeks ago. Did you get a chance to mess with the overflow box? Jake from RC came by to look at it yesterday due to the issue with the bulkheads hitting the plumbing inside the external box. Jake is supposed to get back to me soon but wondering what your impressions were.
