It dissolves injected CO2 fully into the water so very little gas is wasted. It suits aquascapers and planted-tank keepers in South Africa who run pressurised CO2 and want to get the most from every bubble.\u003c\/p\u003e\n\u003cp\u003eStandard ceramic plate diffusers release fine bubbles into the tank, and many of these rise and escape at the water surface before they dissolve. The ISTA reactor works differently. It sits outside the aquarium on your filter line and mixes CO2 into the flowing water until it is fully dissolved. The CO2-rich water then returns to the tank, where it supports healthy, vibrant plant growth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficient CO2 use:\u003c\/strong\u003e The reactor is designed to dissolve CO2 thoroughly into the water, so less gas is lost compared with surface-escaping bubbles from plate diffusers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatented impeller:\u003c\/strong\u003e An internal impeller repeatedly breaks CO2 bubbles down into smaller and smaller bubbles until they are fully dissolved.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrevents gas build-up:\u003c\/strong\u003e The design stops CO2 gas from collecting at the top of the reactor chamber, which helps dissolution stay consistent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo electricity needed:\u003c\/strong\u003e The reactor runs on the water flow from your existing filter, so it needs no extra power source, cable or plug.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact external design:\u003c\/strong\u003e The streamlined body mounts outside the tank, which saves space inside the aquarium and keeps your aquascape uncluttered.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable build:\u003c\/strong\u003e The housing resists acid and impacts, making it a long-lasting part of your CO2 system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow maintenance:\u003c\/strong\u003e It is easy to clean and maintain, so it keeps running smoothly over time.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to Use\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFit the reactor externally on your filter's hose line so that filter water flows through it. Connect your CO2 supply line to the reactor's CO2 inlet. As water passes through, the impeller mixes the incoming CO2 until it dissolves, and the treated water carries on into the aquarium.

If your filter stops during a power cut, water stops moving through the reactor and CO2 will not be dissolved until flow resumes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat hose size does my filter need to use this reactor?\u003c\/strong\u003e\u003cbr\u003e\nThe reactor is made for 12\/16 mm (0.47\"\/0.63\") filter hoses. Check your filter's hose diameter before buying.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich CO2 tubing connects to it?\u003c\/strong\u003e\u003cbr\u003e\nIt is compatible with standard 4\/6 mm (0.16\"\/0.24\") CO2 tubing, the size commonly used with CO2 regulators and bubble counters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is it better than a ceramic plate diffuser?\u003c\/strong\u003e\u003cbr\u003e\nWith a plate diffuser, many bubbles reach the surface and escape before dissolving. This reactor uses a patented impeller to break bubbles down until they are fully dissolved, and it prevents gas from gathering at the top, so far less CO2 is wasted.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it be visible in my aquascape?\u003c\/strong\u003e\u003cbr\u003e\nNo. It mounts externally on the filter line, so nothing sits inside the tank and your layout stays clean.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it difficult to maintain?\u003c\/strong\u003e\u003cbr\u003e\nNo. It is designed to be easy to clean and maintain, and its acid- and impact-resistant body is built for long-term use.\u003c\/p\u003e","brand":"AD","offers":[{"title":"Default Title","offer_id":39282702811190,"sku":"4719856835396","price":399.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0151\/9016\/3510\/products\/ista-external-co2-reactor-efficient-co2-diffusion-aquarium-accessory.jpg?v=1743713308","url":"https:\/\/jungleaquatics.com\/products\/ista-external-co2-reactor","provider":"Jungle Aquatics Pet Store","version":"1.0","type":"link"}
