ISTA CO2 PREMIUM PACK The Ista premium pack is a CO2 controller with included regulator, solenoid valve and bubble counter. The regulator has a hand air-tighten design meaning no extra tools are required to fit this to a CO2 canister. Comes fitted with a Standard UK 3 pin plug. The included bubble counter allows you to read how many BPS (bubbles per second) are being put into the tank. This pack also includes a CO2 indicator which allows for easy monitoring of the CO2 level within your aquarium. The included diffuser is made to be efficient at diffusing the CO2 and has a replaceable ceramic disc.
