I purchased this from petco or petsmart and it was expired. It killed all my fish in the aquarium. I would recommend smelling it and looking at the color to make sure it isn’t expired.

Saved my fish from a new aquarium setup that got sudden spikes. Super easy to use. Large bottle small price and it does the hard work for you. I wish it was a squeeze to measure bottle like kids mouth wash though. Using the lid to measure is frustrating.

This is a great product for the cost. It does what it is supposed to and you don’t need much product to get the required de-chlorination. I like this brand because of the price point and I’ve purchased many times and never had any issues. It also has a nice little measurement thing on the side of the bottle so you know how much to squeeze out and you don’t have to measure it with something else.

You can always count on Tetra products especially the AquaSafe. Follow the directions and you will never lose a fish! Usually I just use rain water but in times with little to no rain I have to use Tap water and AquaSafe always has my water just right for my fish babies to thrive.

I have been using this for years in all 3 of my fish tanks to remove chlorine and metals from tap water. Works perfectly and now also has the added benefit of reducing stress in my fish. I add it monthly as maintenance or during any water changes.

1 teaspoon to 10 gallons...
4 July 2021

1 teaspoon to 10 gallons if fine for those with 10 gallons tanks. Oh you want me to do the math to figure out how much I need for this little tank I bought?That's asinine! On your website should be a easy to find graph. My stupid tank doesn't give me volume, just tank dimensions. I guess my kids are going to get the same fish experience I had, ya get a fish and then it dies a few weeks later.

Great dechlorinater for fish tanks
27 October 2021

I use this with all my fish tanks once they are cycled and no toxins show up in the weekly test. I like that it is immediate and I can safely add the dechlorinated water to the tank without waiting a time period. I recommend this product

My fish thank me
27 October 2016

I use this larger size product for effectiveness and value. The New Orleans water system is recently more heavily laden with chlorine and other constituents that are particularly injurious to pond fish. Out of an abundance of caution, I am using 2-3 times the dosage and premixing in a 35 gallon trash container batches that I will let sit for hours before discharging into the pond. This procedures has been endorsed by two reputable fish pond supply experts in the area. That is why I recommend the larger size for value and standby need.

Not safe for your fish!!
7 December 2021

This stuff is not safe for your fish. I used as directed. I was using regular tap water in a small tank I had; then I upgraded to a bigger, better tank and put this in my tank to help clear up some fog so I wouldn't have to clean the big tank out as much and it left white stuff all over my fish and killed 7 of them. It made them look quite sluggish. After I realized what was causing them to die, I discontinued using this stuff and all 4 that are left are doing well; happy, healthy and growing since I stopped using this Aqua Safe Plus by Tetra. They seem to do well with just my tap water.

Excellent product. Immediately neutralises dangerous chlorine, chloramine, copper, zinc and lead. It also has vitamin B, Iodine & magnesium. Worth buying & a genuine product sold by IndieFur.
