If you want to stop your fishes from, well, sleeping with the fishes, you have to be good at balance. Keeping fish & plants healthy in a tank is a synchronized swim of: buffering pH, removing ammonia & nitrites, detoxifying heavy metals, managing chlorine (and chloramines) and restoring electrolytes and slime coat. Our Water Conditioner not only holds perfect 10s for these acts, but what truly makes our All-in-1 Water Conditioner different is this: our proprietary trade secret formula uses 11 different active ingredients swimming in tandem to eliminate the bad stuff all while adding electrolytes and protective slime coat for your aquatic kin. This one bottle achieves what our competitors sell in 4 different products. From hobbyists to fish fanatics, this will safely make your aquarium water healthier and fish happier.

That’s what makes us better.
That’s what makes us Natural Rapport.


For new aquariums and after water changes, apply 1 capful (5 mL) per 10 gallons (38 liters) of tap water. Overdosing may cause cloudiness.

Dosing is designed to reduce toxins at the following rates: 1.0 ppm (mg/L) Ammonia, 2.0 ppm (mg/L) Chlorine, 3.2 ppm (mg/L) Chloramine

Good for Removing Chlorine

I wasn't totally sure to buy this product based on some of the reviews. Some claimed it did not do what was claimed on the advertisement. I only wanted something that could remove Chlorine from my tap water before putting it my fish tanks. I bought a bottle and tried it according to the mix requirement. In a 300 gallon tank, there were no signs of Chlorine within an hour after adding the product. Since, I have bought 4 more bottles and use it all the time. If anything, it is great for eliminating Chlorine.

Peace of mind

Without continually testing my small pond and indoor aquarium water for balanced chemical levels, regularly using this additive gives me the peace of mind to know that chemical levels are automatically balanced. The evidence is in the behavior of the fish, who have consistently remained active and healthy since I started using Natural Rapport. My only complaints are with the dosing cap that has no markings and allows dripping down the sides of the bottle, as well as the product not being available in a larger size. Priced consistently with other water conditioning products, but in my opinion, does considerably more good.
