5.0 out of 5 starsKeeps your Beta healthy!!
By BeachShiba on July 16, 2010
Size: 8.4-Ounce Verified Purchase
7 drops in an average little fish bowl with normal water and I have had a Beta for over two years now using nothing but this! Every couple of weeks, I rinse the bowl, replace water, put the drops in, done deal. Good stuff. Keeps your fish healthy. The end.

4.0 out of 5 starsKeeps tank pretty clear
By Amazon Addict on November 26, 2010
Size: 8.4-Ounce Verified Purchase
Previous reviews were helpful. I use it everytime I change the water. The water stays clean for about two weeks easily. It says aquarium for fish but I have been using it for my turtle aquarium and it has worked out fine. The filmy residue does appear but just make sure not to use in excess and it should not be an issue. Also, if you are using this for turtles, frequent baths also help to remove the film from the shell.

2.0 out of 5 starsThere is better stuff out there that isn't as costly
By heaya on February 19, 2012
Size: 8.4-Ounce Verified Purchase
So, I used this initially when I first got an aquarium because someone else told me they used it. At first all was fine, it does what it needs to do by getting rid of the ammonia/chlorine from tap water.
Here's the thing, these water conditioners that have "slime coat" crap in them, the way they work is by BURNING the fish, the irritation induces them to produce their slime coat. I wasn't aware of this, but when I was using it, I noticed that some of my fish would always flash - swim rapidly up and down the glass - I didn't know if it was them being "excited" to have a water change, no, they were just in pain/stressed.
Anyway, after coming to the end of my bottle in like 1 month's time, I ordered Seachem Safe (powder version of Prime). My fish no longer flash, and it works better, way more cost efficient. Save your money, buy Safe or Prime, both are way better.

5.0 out of 5 starsPerfect for beginner and beyond
By K. Baggan on November 6, 2006
Size: 16.9-Ounce Verified Purchase
Whenever you add new tap water to your aquarium the chemistry of the water changes, these changes can be very harmful to the fish depending on how drastic they are. So it's recommended you do a 10-20% water change every week to your aquarium to help reduce chemicals like ammonia and dilute the nitrites etc. But the tap water also carries harmful chlorine and chloramine.

Tetra AquaSafe removes both and enhances the stress coat produced by your fish, thus making it perfect to condition your aquarium. I've had no problems whatsoever with it, and it has greatly improved the overall health of my fish.

I personally don't use it with every water change (although its recommended that you do) but that's usually based on the amt being added and the condition of my tap water.

Use 5ml to treat 10gal

5.0 out of 5 starsAQUASAFE WATER CONDITIONER
By Amazon Customer on February 11, 2010
Size: 1.69-Ounce Verified Purchase
EACH 1.69 OZ BOTTLE (50ML) TREATS 100 GALLONS. DIRECTIONS ARE: 7 DROPS PER GALLON OR ONE CAPFUL (5ML) FOR 10 GALLONS. I PREFER THIS PRODUCT OVER ANOTHER WATER CONDITIONER BECAUSE IT GIVES DIRECTIONS TO TREAT EACH GALLON, HELPFUL FOR SMALLER BETTA TANKS OR PARTIAL WATER CHANGES IN OTHER SMALL TANKS.

The first, and only water conditioner I have ever used for my betta. Spike is now 3yrs old, and continues to thrive. I attribute that in part to AquaSafe water conditioner.

5.0 out of 5 starsgreat for 1000 gallon ponds
By Laurie L. Mcgee on July 4, 2009
Size: 8.4-Ounce
We just got done setting up a 1000 gallon pond in our backyard. The bottle originally says "for up to 500 gallons". We have 10 assorted fish in our pond. And they are doing great. If you use this product for a pond you might consider adding it in an area of the pond with a pump. So the fluid can distrubute quickly. With in seconds the pond was ready for fish.

3.0 out of 5 starsA good chlorine removing solution for aquariums
By Bill P. on May 16, 2013
Size: 8.4-Ounce Verified Purchase
First, let me say that I was told I was purchasing an 8-oz container of Nutrafin Betta Bowl Conditioner. When my box arrived, I had this product in the box in stead. Not sure what happened in the mix up, but I ended up holding on to this product. This review is neutral and does not reflect the fact that the mix-up happened.

Considering the volume of the container I got for the price, this is more than a good deal for a chlorine treatment. I usually use API Stress-coat, which, according to both bottles, should offer the same features. I gave this one a try one week during my regular water changes, and my fish seemed to behave normally. Nothing wrong with it. The item came as it is packaged in stores, with no signs of defects. It is a water dechlorinator for aquariums. That's what the bottle says, and that's what it does. No complaints.

I have one big problem with all of Tetra's products, and that is that these bottles are NOT SEALED at the top. It's a goopy liquid I'm supposed to pour into my aquarium. I am not qualified to determine whether what's in the bottle is what the bottle says it has in it. When I get API products, they come with a seal on top. This one, there's no telling if what I'm buying is what's in the bottle. Since this is an online order there's less risk, but I completely avoid Tetra products in stores because they're open containers. Do I know whether the employees thought mixing them around would be funny? Or if someone opened one up and got something in the bottle? NO! If it's not something I'd be comfortable with for human use, I would never use such a product on my pets. Sounds crazy, but you just never know. Fish can be delicate, and costly. One wrong move like that and you could ruin a tank.
