Depends on what you mean by "good product" I guess. I think it is fine as water conditioner, it neutralizes heavy metals and chlorine. But, some of it's claims are just silly. Fish regenerate their own slime coats very quickly and don't need synthetic slime coatings at all. Not only that, but what is the point of putting aloe vera in Stress Coat? Aloe vera is a mild pain reducer and helps keeps damaged tissues moist. Fish, living in water, have no problems keeping their tissues moist! And, unless they are hurt, why would they need a pain reducer? I really think that the only reason Aloe Vera is added is because people read it and think "oh! that's natural! it has to be better than some chemical!" But, then again, Stress Coat says is makes a synthetic slime coat (does anyone even know what the synthetic coat is?) and that is about as far from natural as you can get. I'm sorry, but like I said, it all seems silly.
Not that Stress Coat is super expensive, but a plain jane dechlorinator and heavy metal detoxifier is good enough for me.
