I want to find out if this is a good one to buy. Does anyone have problems with this reactor? I have a 120 gal tank and this one is rated up to 270 gal.
Not too many people will have experiences with this reactor since it is an internal model that is significantly bulky. I have seen it in use in a tank in Asia (Taiwan or Japan I forget) and it looks to be decent enough. But I don't have any first hand experiences. I personally would never consider a submerged Ca reactor just for the difficulty of maintainance in my system.
If you can hold off on a reactor for a year and don't mind DIY, Fergy teaches an outstanding MACO course that helps you build a great Ca reactor at a very affordable price (all parts are provided and can be precut, depending on package you purchase). He'll be teaching a skimmer course soon so if you're looking for a skimmer, there's no better time www.reefs.org/maco/
