Deltec Deltec PF509 Fluidised Calcium Reactor with Media

The PF509 is the starting model of a new fourth 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. The reactor comes complete with 2 kg of Rowalith C+ media and 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. Technical Data

Tips on use of a Deltec Calcium Reactor 1. Always keep the unit topped up to the fill line rather than letting the media fully disolve and then replacing a large amount at one time. The only real difference between one model and the next one up is the volume of media that it holds so if you run you reactor at half full you may as well have bought the next reactor down. 2. The Deltec reactor is fitted with a port for a pH probe however we do not believe that you must invest in such additional equipment to run the reactor. We prefer that the drip rate and bubble rates are set by measuring the dKH of the effluent from the reactor. This should be set at about 45-50 dKH which corresponds to 800 - 900 ppm of calcium. It is a simple matter therefore to set this up and then to adjust the length of time during the day that the reactor is operated until the correct calcium level is maintained in the aquarium. 3. Always try to run the reactor during the lighting period of the aquarium so that the natural increase of the pH in the tank due to photosynthesis counteracts the lowering effect of the CO2 addition. 4. Never overfluidise the media or it will flush all of the fine particals into your sump. The fluid above the media should be clear not cloudy.
