Black Corundum Air Stone Disc, 2 Pack 50mm Mini Aquarium Aerator

About This

• Compact 50mm Size for Office & Desktop Betta Tanks The slim round air stone fits tiny 0.5–4 gallon desktop aquariums, perfect for office desks, bedroom and student dorm. It releases mild steady bubbles without strong water flow, keeps betta fish calm and stress-free. Single disc works well for small freshwater tanks under 30 gallons
• Must-Have Aeration Accessory For Home Hydroponic Growing Ideal match for 10–30L mini DWC hydroponic buckets for lettuce, basil, mint and strawberry. Continuous bubbling raises oxygen in nutrient solution, effectively prevents plant root rot and removes stale water odor. Two stones support dual planting buckets at the same time
• 2 Pack Flexible Usage Design For Different Demands You can use two stones separately for two mini fish tanks, or one fish tank plus one hydroponic bucket. For 30–70 gallon medium freshwater tanks and dual-slot hydroponic systems, place both discs together for even full-tank oxygen distribution. One spare stone for quick replacement when clogged
• Clear Compatibility & Usage Notice Works with low-power 3W–5W silent air pumps, only fit 0.5–70 gallon FRESHWATER aquariums. NOT suitable for saltwater reef coral tanks, fish tanks over 70 gallons, large outdoor ponds and chlorine-containing swimming pools. Air pump and tubing are not included in the package
