Review on 🐠 TankFirst Complete Aquarium Water Conditioner: Effortlessly Remove Harmful Substances for Optimal Fish Tank Health by Natalie Martin

I use this product for Flash, our 4 year old goldfish who lives in an old school aquarium on the kitchen counter. I've had trouble with water changes before and on several occasions we almost lost the Flash! This product is great! I add 1/2 capful to a large jug of water and let it sit all day - I know it says ready to use but I'm careful. The Flash is always so happy when he changes his waters with this thing - he swims so fast. This is a definite difference from other products I've used in the past. And the water is so clear! This product is very clean and not thick - highly recommended.
