Rated 5 out of 5★ by Guppy Aqua safe one of the best Aqua safe by tetra is one of the best product to remove chlorine and other harmful substances from the tap water. I love this product after purchasing it from Germany. It work well for all aquarium fishes and I personally kept guppies and though they are hardy but is challenging to keep them ESP the water is not treated. So far is the best solution. I can see my fishes swim lively after I do water partial water changes with aqua safe added to my tap water . 01/29/2013
Rated 5 out of 5★ by Fishguy123 Aqua safe is great! I have recently purchased a new aquarium and only apply tetra aqua safe because I know it is from a company that I can trust. It uses special vitamins and minerals to dechlorinate and condition the water. My fish have been very happy and healthy thanks to aqua safe! 03/20/2013
