Review: Excellent value. Have been using for years. Would never buy anthing but this. - I swear by this stuff. It's perfect for water changes. I use it in all my aquariums and in my pond. I never mix water first. I just do it in the tank. I do add water slowly though. It has no smell or color. It works very fast. It is highly effective. I add one cap full for every 30 gallons of water in my tank and it always works. It says add such and such for every gallon that you add, but I do the math by the water volume of my tank since I am adding tap water directly to my tank. A couple of drops is all you need for a gallon if you are only topping it off. I do about 70% water changes biweekly using this stuff. If you are having dead fish most likely the issue is because of temp, adding it too fast, or you just need to add more. I have even added way more than it needed by accident. It had literally no effect on my fish or plants at all. Very hard to overdose your tank unless you dump in the whole bottle. I do wear gloves when using this product. Can't be too careful. And eye protection too.

## 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.
