An UltraZap spawning brush for koi and pond breeders, available in 600×150mm and 2000×150mm. The fine bristles give spawning fish a rough surface to deposit eggs on, and while they are in the water the brushes double as biological media, hosting the bacteria that keep ammonia in check.

Use them in a breeding pond, a dedicated spawn tank, or an aquarium or fish tank set up for breeding.
