zeo as well as any of the other systems ran basically manipulate the colors of the corals, it will keep nitrates phosphate and others at 0 will allowing to feed more, i personally once my brightwell runs out will not be using any of these systems anymore, do they help, yes, do i really need it, no, with my husbandry i have and the equipment. as a serious reefer, the thing's your planning to use as a selling point wouldnt be a selling point for me, seeing i dont use l.e.d, don't use zeo, and to be honest as a person who runs a million dollar business i couldnt ever imagine saying what you just said to someone on here and ever think my business had a chance, word of mouth is the best advertisement there is. LFS owner gets nice stuff but is a dick, therefor i dont go there, this isnt a personal attack with what was said, but not something i would openly being saying in a forum, while in the process of trying to open a business, and still hope it works out and best of luck, btw any owner or or persona selling something is always going to tell you it isnt that hard and so on as zeo has told you. what do you plan to do if you take a week or longer vacation ? reason alot of the well known vendors site's dont use this product or others like it
