I'm sure. But that stuff can't be bought here. Even Dr. Tims takes 2 weeks to get here if you're lucky. No dealers in the country carry these products, so I don't have the luxury to chose.I just cycled my 130 with Fritz Zyme, I had never done this and had been away from the hobby a long time so I was a little anxious, but I put two 32oz bottles in the tank, two 3 plus inch tangs and tested daily for two weeks. As promised, the tank cycled and I have no ammonia readings to speak of that was roughly two weeks ago and the fish are happy.
To my surprise, this stuff works lol
