I’ve used this conditioner for three months now and my betta fish has shown no signs of stress. The water changes are much easier since I don’t have to worry about heavy metals anymore. Works well with my daily water changes.

It’s simple to use and effective. My community tank has been stable since I started using it. No fish have shown any symptoms of metal toxicity.

Great product for new aquarium owners. I bought it after reading about copper in tap water. My fish are active and healthy now. Easy to mix and works immediately.
