All along, I have the mindset that AC will rid off active bacteria. Won't it be a waste to having to cycle our tank to generate active bacteria?

Skysky, I believe NA boss was referring to this little sachet of AC he is selling and using it in his 3ft tank. He also did mention that its lifespan is about a month and you would need to replace it before the impurities absorded be released back to the tank. Not in bits but the whole gang at one go. That's the main reason I dare not experiement with it... fearing I may forget to change. Lazy me...
