The Only All-In-1 Water Conditioner Fish Need

  • Make a Selection

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

Seems to work!

I started a new tank and they seemed happy for a week but then they just sat at the bottom and two of them died. I bought this hoping to help and they all started swimming around again in only a few minutes! So happy! I was skeptical because all the other treatments were so much more expensive but it seems to have done the trick! I started a 20 gallon tank with 2 mollies, 4 (now 2) guppies, an African dwarf frog and a betta.

This is the best

This is the best water conditioner I have tried. I have one beta, three snails and one Cory catfish. The product works so well I got the gravel cleaner and use that to wash the gravel until the water is clear. Add a cap full to the aquarium when I clean it and it keeps the water clear and clean. I literally add 5ml of the conditioner every time I clean the tank and its set.

Thank you so much for sharing your positive experience and for being a NattyRap customer. It's always a pleasure to hear from satisfied customers!

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.
