How long should be waited after dechlorinating water with Amquel Plus should be waited before adding the water to the tank. I know Prime is recommended but I want to use this bottle first. I'm supposing the recommended time is more than I spent, because I appear to have experienced a die back in the bacteria that are converting fish food into amonia, because they've gone from producing nearly 0.8 ppm in 24 hours to little if any. My tank also appears to have regained the bacterial bloom that had disappeared just before the water change. :eek3:
