5.0 out of 5 starsHelping with fin regrowth
By Kim Karas VINE VOICE on March 25, 2012
Size: 16 oz Verified Purchase
Two of my fish had their fins damaged by an aggressive tank mate. While this is a nice water conditioner, I bought it with specific hopes that it would aid in my fishes tail fins regrowth and it has done just that. I was very upset at the damage and didn't know how well mother nature alone would take care of it and this stress coat fish and tap water conditioner has definitely delighted me with it's efficiency. Pay close attention to the dosing. Extra size dose is recommended for fin damage.

5.0 out of 5 starsWorks as advertised
By igotaducky on November 2, 2012
Size: 16 oz Verified Purchase
I rescued some fish from an overstocked tank and purchased this to help heal their battle scars as well as treat my tap water during water changes. Within 2 days of the first dose I can see improvements in the wounds on my fish. I will continue to use this product.

5.0 out of 5 starsGreat for Water Changes
By soulman on January 6, 2012
Size: 16 oz Verified Purchase
I use this product with every water change or when introducing new fish. I typically change twenty gallons out on a 55 gallon tank. I treat the 20 gallons full strength per instructions, which when added back to the tank would put it just under half strength. My fish are going on seven years of age, so I am very please with this product.

4.0 out of 5 starsGood Product but Somewhat Difficult to Read Measuring Cup
By Absolver on November 20, 2013
Size: 16 oz Verified Purchase
Product appears to work well. The fish seem OK. Difficult to really evaluate without a laboratory. Only complaint is that the measuring cup (included in the bottle cap) is a bit difficult to read. I used to use Topfin (Petsmart store brand) and their cap-cups are more translucent and easier to use.

Pro Tip: the Topfin brand caps fit the API brand bottles perfectly. I discovered this when I was switching brands and saved all my old Topfin caps.

5.0 out of 5 starsLove this stuff: Using regularly since 1999.
By University Doc on August 25, 2012
Size: 16 oz
There are a great deal of water conditioners out there on the market for the fish tank. This is one that I've used regulary since 1999. I use it to condition my water for water changes, topping off the tank and when setting up a new tank. It removes both chlorine and chloramine from tap water. It also reduces fish stress and heals any damaged tissue, torn fins, and skin wounds. It also replaces the natural secretion of slime that is interrupted by handling, shipping, fish fighting, or other forms of stress and reduces the susceptibility to disease and infection. It is a great product, which I have no trouble recommending to others. I usually buy the larger size, but when in a pinch I buy this size.
