my life long knowledge (over 20 years)and hard work in the salt water hobby has evolved into this settup, its not all the way there yet but damm close ,to actually see results on a daily basis is very rewarding .right now there is 800 gallons but am adding another 400 as soon as vats finished. there is no way to describe the feeling of satisfaction that goes along with successful life support of some of natures finest creations i only hope i can find even better ways to prolong their lives
