The transaction was fast. professional, well packaged. Recommend seller.
Works well and does exactly what it is advertised to do. Came in a nicely packed box and does a bit more than the dechlorinator I was using. My fish is acting as he normally does, which I also like :)
I switched from Prime to this because I feel like this has more added benefits (slime coat protection). I haven't noticed any difference in the behavior of my fish. I would say both products are just fine, but I like this one as well.
