Sugar is fermented in a plastic bottle to produce CO₂, which is then introduced directly into the aquarium via a diffuser.\u003c\/p\u003e\n\u003cp\u003eDepending on room temperature (optimally 20–25°C), the kit supplies your plants with CO₂ for up to 2 months. No complex equipment, no cylinders — just a hassle-free way to maintain optimal CO₂ levels and encourage lush, healthy plant growth.\u003c\/p\u003e\n\u003cp\u003e✅ \u003cstrong\u003eTracked UK delivery\u003c\/strong\u003e  |  ✅ \u003cstrong\u003eCarefully packed\u003c\/strong\u003e  |  ✅ \u003cstrong\u003eSuitable for Caridina \u0026amp; Neocaridina tanks\u003c\/strong\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBio CO₂ Bottle\u003c\/li\u003e\n\u003cli\u003eCO₂ Powder Mix\u003c\/li\u003e\n\u003cli\u003eCO₂ Tubing transparent 4\/6mm — 100cm\u003c\/li\u003e\n\u003cli\u003eCO₂ Diffuser 17mm Membrane — 14cm\u003c\/li\u003e\n\u003cli\u003e2 Suction Cups\u003c\/li\u003e\n\u003cli\u003eCO₂ Activator ×5\u003c\/li\u003e\n\u003cli\u003eInstruction Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch4\u003eQuick Start Guide\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMix Bio CO₂ powder with 300ml water and leave to rest for 24 hours\u003c\/li\u003e\n\u003cli\u003eAdd Bio Activator with 200ml water\u003c\/li\u003e\n\u003cli\u003eConnect the CO₂ diffuser to the hose — ready to go\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch4\u003eKey Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 2 months of CO₂ supply per fill\u003c\/li\u003e\n\u003cli\u003eSimple yeast fermentation — no cylinders or complex equipment\u003c\/li\u003e\n\u003cli\u003eSafe, effective and eco-friendly\u003c\/li\u003e\n\u003cli\u003eIdeal for small and nano aquariums\u003c\/li\u003e\n\u003cli\u003eComplete kit — everything included to get started\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the CO₂ last?\u003c\/strong\u003e\u003cbr\u003eUp to 2 months depending on room temperature. Optimal performance is achieved between 20–25°C. Cooler rooms will slow fermentation and reduce CO₂ output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhen should I add the CO₂ Activator?\u003c\/strong\u003e\u003cbr\u003eRefill the CO₂ Activator every 14 days or when CO₂ production drops to 5 bubbles per minute. This restarts the fermentation process and restores CO₂ output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it suitable for large aquariums?\u003c\/strong\u003e\u003cbr\u003eThis kit is designed for small and nano aquariums. For tanks over 60 litres, a pressurised CO₂ system is recommended for consistent and controllable CO₂ delivery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this CO₂ system safe for shrimp?\u003c\/strong\u003e\u003cbr\u003eYes, when used correctly. Maintain a stable CO₂ level and ensure adequate surface agitation to prevent CO₂ from building up excessively. Avoid running CO₂ at night when plants are not photosynthesising. Suitable for tanks housing Neocaridina and Caridina shrimp.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I get refills for this kit?\u003c\/strong\u003e\u003cbr\u003eYes.
