It also detoxifies heavy metals in tap water. The formula of API TAP WATER CONDITIONER incredibly concentrated. You only need up to 3 ml to treat 10 gallons of water.

Review: Healthier water for healthier plants - Looking forward to healthier and happier plants. Going by all the reviews, this product seems to stand the test of time. I haven’t used it yet, but I’m certain it is much more effective, and of way higher quality, than tap water. No smell. And the cap has a 1 mL measurement which is really nice for me, since I use gallon, or less, containers, for watering. Great expiration date for lasting a long time.

## Questions & Answers

**Q: What is the difference between the 1 gallon item at $37.28  and the 128 ounce item at $19.46?**
A: $17.82

**Q: Can I use it for the water I use to water my plants? My plants don't do well with my tap water. Thanks :-)**
A: I add this before every watering for medical cannabis plants. 
1 mL per 5 gallons of water. Had severe problems before using this.

**Q: What's the difference between the tap water conditioner, the stress coat conditoner & the stress zyme. I'm confused, do I need all three for my biorb?**
A: Looking at the ounces needed per gallon, the stress coat treats 60 gallons per ounce while the tap water conditioner treats 600 gallons per ounce. It looks like the stress coat does more things to protect the fish, but the tap water conditioner will treat more tap water per bottle.

**Q: I have had this product for about 2 weeks. In the past few days it began to smell reallly bad. It smells like old faithful. Does anyone elses smell?**
A: i keep mine in the refrigerator to avoid that situation from happening.  It is probably spoiled.  First, check the expiration date on the bottle, if it is still supposed to be good, you may want to look around the storage area you had it in for local heat sources that can sour it, such as: periods of direct sunlight during the day, sitting in front of the heat vent, etc.  These can spoil the product in short order.  Like I said, I keep mine in the fridge just to be safe, (all my liquids for my tank are in the fridge, even tho they do not require it.)   I hope that helps.  for what it is worth, the smell I get from a fresh one has a tang of aloe vera to it, smelling like a swimming pool kinda smell, minus the chlorine.

### ⭐⭐⭐⭐⭐ Affordable, and Effective Water Conditioner
*by M***W on August 15, 2025*

I’ve been using API Tap Water Conditioner for years, and it has consistently delivered great results. For me, it’s the perfect balance of effectiveness and price, it works just as well as higher-end brands, but at a fraction of the cost. A 16oz bottle lasts me around 5 months while maintaining two aquariums (a 20-gallon and a 40-gallon), which makes it an incredible value. The built-in measuring cap is a simple but very handy feature, it takes all the guesswork out of dosing. My routine is to add half the recommended dose while refilling the tank and the other half once it’s completely filled. In all the time I’ve used this conditioner, I’ve never had a single issue with water quality or fish health related to tap water treatment. It’s easy, dependable, and budget-friendly, exactly what I want in a staple aquarium product. Highly recommended for any fishkeeper.
