PNS HomeGro (2.5 gal)

Take control of your aquarium’s health with PNS HomeGro, a unique at-home kit that allows any aquarist—beginner or expert—to grow a full 2.5 gallons of fresh PNS ProBio. This isn’t just a jug of bacteria; it’s an experience. With everything you need included, HomeGro makes it simple and rewarding to produce your own batch of the same live Purple Non-Sulfur Bacteria (PNSB) that powers Hydrospace’s legendary PNS ProBio “red bottle.” Instead of buying multiple small bottles, HomeGro lets you prepare a large, ready-to-use supply right in your own space. It’s cost-effective, educational, and above all, a fun and empowering way to connect with your aquarium at the microbiological level.
