PacificSun really surprised us with their original CalcFeeder Pro which uses an optical sensor to automatically monitor dissolution rate, and now they’ve gone ahead and made an even smaller model. The CalcFeeder AC Mini is the newest model in their automatic calcium reactor with a footprint that is only 13 by 8 inches in area.
This compact Auto Calcium Reactor design can be used in-sump or externally, and it includes the CalcFeeder Pro controller for competely independent operation from a pH controller. This controller regulates the amount of CO2 added to the gas reaction chamber through feedback from four optical sensors, and the built-in stepper-motor powered dosing pump precisely adds a steady rate of new aquarium water for optimal dissolution of the calcium carbonate aragonite reactor media.
With a built-in dosing pump, solenoid valve the only thing you need to add to this setup is your own source of carbon dioxide and CO2 regulator. This new model fo PacificSun’s innovative calcium reactor is probably the most high tech small calcium reactor of its size and should be very appealing to the small volume reef tanks with very high calcium adn alkalinity demands. The estimated retail price of the CalcFeeder AC Mini from PacificSun will carry a retail price of 899€ (around US$1118) and will start shipping the first week of February. [PacSun]
