This Nitratefilter 100 is a biological filgter which can be used in or out-of-sump with the reactor volume capacity of about 2 litres of either sulphur or siporax media for colonization of bacteria to transform nirate into nitrogen.
Opted for the sulphur beads instead of siporax as the sulphur bead is both a nutrient and substrate in one.
The filter comes with a Eheim 1250 28W pump and it also requires a feed-pump to draw aquaria water to the reactor.
