My 100g zeo tank

[Ruth]

Oh my goodness - I don't even know what my initial cost was as it was at least a year ago that I initially started to aquire stuff. I did buy a bunch of additives on zeovit from a couple of people that decided they didn't want to do it anymore and that was quite a savings.
I would guess - and I mean guess - that the cost of my buying the stuff that was required to start with the basics was somewhere around $300, including a second hand zeo reactor that was not that good a deal as it broke soon after. I am sure that if you inquire with Paul at Reef Perfections or with Hidden Reef or even Ocean Aquatics (who I believe are going to carry the zeo line) they can probably give you a lot better idea.
