calcium reactor

[westhawt]

I am interested in purchasing a calcium reactor for a 180 gallon tank. Does anybody have any suggestions in regards to quality... and what type of regulator would you suggest?

Geo for the reactor, and aquariumplants.com electronic regulator. By far, the best combo I have used- simple to dial in, and consistent.

can't go wrong with a geo.. do it right the first time and get it. I made the mistake of buying a used cheap model and later ended buying a geo.
