PF509 Calcium Reactor
The PF509 is the starting model of the fifth generation of Deltec Fluidised Calcium Reactors which now comes with a full bayonet fitting on the top for full and easy access to the media.
This may be the baby of the family but with its fluidising action it is capable of providing the required calcium levels on tanks up to 100 UK gallons - 450 litres - 119 US gallons. Comes supplied with 2kg of Rowalith C+ media.
If you add this to one of the D-D saltwater CO2 sets then you will have everything that you need to plug and play.
