Tropical Querex 30ml

QUEREX
An oak bark extract for blackwater aquariums. Like TORFIN COMPLEX, QUEREX acidifies water, reduces hardness, and provides beneficial tannins that inhibit fungal and bacterial growth. It is particularly beneficial for discus, angelfish, South American cichlids, characins, Colisa, Corydoras, and other soft-water species.
For optimal results, use QUEREX alongside TORFIN COMPLEX.
