Fits the ista nano system. I contacted co2supermarket in advance to ask if they knew if it fitted and they replied promptly to say it would. Slightly smaller than the 95g supplied in the ista kit, but works perfectly. Fits the ista nano system.

Triple dosed this for a couple of weeks and successfully killed off an infestation of BBA. Have dropped the dosage down since then but still use in conjunction with pressurised co2. Plants have never grown as well as they are growing now. Truly awesome. Triple dosed this for a couple of weeks and successfully killed off an infestation of BBA.
