Neutralisation filter NF, mineralisation filter

The neutralisation filter NF is filled with a pure lime material and is thus able to raise the slightly acidic pH value of a sulphur nitrate filter ADN. This version of the neutralization should be used if no Turbo Chalk Reactor is installed in the system. This neutralization filter can also be connected behind conventional lime reactors: the neutralization filter should have a volume similar to that of the lime reactor. Do not use this filter behind a Turbo Chalk Reactor!

This filter can also be used to enrich reverse osmosis water with minerals (GH and KH) - especially in heavily populated soft water aquariums. 

Spare parts can be found at the respective size under "spare parts".
