GEO Calcium Reactor including all parts and full Co2 tank. The Co2 regulator was bubbling inconsistently. Don't know if it is a simple adjustment issue or needs replacing. Other that that, all parts worked properly. Includes a Milwaukee PH regulator. Purchased system new 2 years ago. Do not remember the model number but chamber measures 19" tall by 6 " wide. Asking $140. Local pickup only.
