Vart har du läst detta? Nån som vet hur Deltecs kalkreaktor serie funkar med svävande media?? Rowalith C+ Rowalith is mined from ancient fossil beds and is guaranteed to be 100% phosphate free. Additionally, Rowalith C+ contains all of the trace elements in the correct proportions that make up the coral skeleton. Notes on Use of ROWALith C+: This material must be washed very thoroughly before placing inside your Deltec Fluidized Reactor; if you do not do this, the reactor will run cloudy. RowaLith C+ is a natural material specially chosen to produce the highest calcium output from your Deltec Fluidized Reactor. Set the reactor to run between 30 to 40 dKH. Measure the water from the reactor after allowing it to run for a few hours, from the output flow. Due to the efficiency of the fluidized reactor, constant top up of this material will be required. Please ensure that the calcium levels in your aquarium do not exceed 450mg/l.
