Biorb aquarium service kit ×4

Four service kits for the biorb aquarium. Each box contains a sealed filter, a cleaner pad, a 5ml water conditioner, and a 5ml biological booster. One box is a little damaged, but the filter is perfectly fine. Each kit retails for $15+ on amazon. I no longer have my biorb, so I no longer have a need for these. Great deal! outstanding for everyday use. first-class materials and excellent craftsmanship ensure long-lasting durability.
