Seeing as one of our favorite new calcium reactors is the simplistic H&S line, it is painful just to look at this tabletop cold fusion device which Aquacare claims is a calcium reactor. The TurboChalk’s need for so many ports, fittings and chambers may be worth the eye sore if the unit is as efficient as the company claims at using very little CO2 while minimizing the gas’s return to the system water. We can’t tell you exactly which chamber is which but the unit includes a gas mixing chamber, gasing off chamber, a sediment prefilter and maybe even a phosphate removing chamber when it is all said and done. All that and no bubble counter? The reactor is designed to use Aquacare’s unique spherical “chalk” which allows for high water velocity and they also have a magnesium reactor media available too. The unit above is rated for 130 gallons and priced at $579, available only at Aquarium Specialty.
