Neptun Flow-through filter set

(This text is machine translated) The Neptun flow-through filter set NCTF-O 4000 UV guarantees clear water thanks to an ideally coordinated combination of filter system and pump with effective UVC technology. Thus, an oxygen enrichment is ensured by special water flow. Flow-through filters are used in medium-sized and large ponds or koi ponds. They are above the water level so that the water flows back into the pond without pressure.
