I've been using it for a little while now. Used about half of the first container, and I just got a second one before it runs out. I don't raise fish for culinary use, but I will be growing vegetables using fish water, so an ammonia neutralizer that's safe to use with food is a nice positive.
I live in a rural area. Our water company adds so much chlorine that you can smell it right out of the tap. This product has been a life saver for my fish and plants. I don't have to buy buckets of the other liquid dechlorinator anymore. Thanks to ACCR ProI can keep my fish and plants happy!
Great water conditioner. More economical than Safe. Only suggestion is that Aquarium Co-Op carry the larger size. Other than that, highly recommended.
If your looking to save money buy this product.
Haven't had any deaths yet, though it's only been used on snails thus far
