Aquario Neo CO2 Refill - DIY CO2 Kit

Once your Aquario Neo DIY CO₂ Kit runs its course after 50 to 60 days and the underlying stabilizer gel is completely spent, you don't need to throw away your hardware or buy an entirely new system. The Aquario Neo CO₂ Refill Pack is an inexpensive, mess-free maintenance pouch designed to completely reset your original bottle. Packed with a fresh dose of specialized gel matrix powder and matching active bio-yeast packets, it brings your carbon injection system straight back to peak output so your planted aquascape never suffers from a sudden nutritional slump.
