F/S is a MCR 2nd calcium reactor chamber. It is 13" high, the diameter is 5 1/2". and uses 1/4" jasco or john guest fittings. Fittings not included. Can be use also with other media like carbon, PO4 media remover, etc as a separate unit or modifiy it for the DIYer as a calcium reactor. Asking $60.00. Excellent condition. Used only six months. I now run the effuent from the calcium reactor into my refugium to uptake the excess CO2. Can p/u in Astoria, Queens, NY during the work week or New Hyde Park, Nassau County, NY on weekends.
