ISTA 0.5L CO2 Refillable Face Up Cylinder Complete Kit I-674

ISTA CO2 cylinder system is a reliable source of carbon dioxide for aquarium. The system is TUV certified for safety. Full accessories included. Ready to use immediately.


With a reliable supply of carbon dioxide, you can create a beautiful, jungle-like aquarium filled with green, leafy aquatic plants, clear water and active frolicking fishes. This is because carbon dioxide is one of the essential components for photosynthesis, and a lack of CO2 would stunt the growth of plants, cause leaves and stems to become pale, and trigger algae growth.

The ISTA 0.5L CO2 Refillable Face Up Cylinder Complete Kit I-674 is an easy and effective way to get high-quality and sufficient carbon dioxide into your planted aquarium. The cylinder contains pure liquefied CO2, and with this system you can conveniently control the amount of carbon dioxide gas to release on demand into your aquarium water.


  • Aluminum CO2 flow regulator provides easy assembling, constant and reliable CO2 dosing rate.
  • 2 in 1 CO2 diffuser provides clear CO2 bubble reading and the best CO2 diffusing effect.
  • Stainless spring design check valve assures most reliable function of stopping backflow. Fastening node assures no bursting out of air tube.
  • Seamless aluminum CO2 cylinder.
  • Stylish design brings additional elegancy to your aquarium set up.


  • Passed the international TUV certification
  • High pressure resistant
  • Seamless, non-leak aluminum bottle
  • Supporting base keeps CO2 cylinder in position avoiding any potential damage to the CO2 regulator.
