4Pcs Aquarium CO2 Generator Kit for Live Plants, DIY Diffuser System Air Pump Tool

Want to bring your planted aquarium to life? This 4pcs aquarium CO2 generator and CO2 diffuser kit is designed for aquatic plant lovers, offering a simple and affordable way to supply carbon to live plants. WHAT'S INCLUDED: 1 ceramic CO2 diffuser, 1 airline tube, 1 check valve, and 1 suction cup (subject to actual product), everything you need to start building a DIY CO2 system for planted tanks. HOW IT WORKS: Connect the CO2 generator to a DIY or dedicated bottle, gas travels through the tubing and check valve, then the ceramic diffuser atomizes it into fine bubbles that dissolve in water and are absorbed by plants. APPLICATION: Ideal for freshwater planted tanks, aquascaping setups, and small fish tanks. The 4mm/6mm tubing compatibility works with common air pumps, CO2 bottles, or DIY generators. USAGE TIPS: Use a bubble counter to monitor flow; install the check valve following the arrow direction; clean the ceramic disc regularly to maintain atomization. For higher CO2 levels, add more diffusers or adjust placement. OUR PROMISE: Each DIY CO2 tool kit is inspected before shipping. If any part is missing or you have questions, contact us anytime and we will make it right.
