Sodium Thiosulfate
Thank you Ken for saving me a fortune on dechlorinator. I did the math, and to treat the same amount of water as the Sodium Thiosulphate, it would have cost me well over a thousand dollars for the pet store stuff. I am so grateful, that I intend to spend some of my saving's at , where the service is outstanding and the shipping is scary fast. Thanks again and I really do appreciate it.
Sodium Thiosulfate
Save hundreds $$$
I am so happy to find this chemical at a reasonable price. I had went to several retailers looking for sodium thiosulfate and got a glazed over look on everyone's face except for a pharmacist....and he had no idea where I could find some. I have more gallons of aquarium water to care for in my home than any of the local pet stores so this will save me a lot of money. Thanks Ken's !
Sodium Thiosulfate
Great Product
As always Ken delivered exceptional service. Sodium Thiosulfate is a great dechlor without the extra cost. Buying the product in dry form allows for hobbyist that maintain multiple aquariums a great product that will not break the bank. You cannot get a better package either, simple one pound bags that convert over to one gallon mix. Why buy anything else for chlorine removal!!

Lovin Ken's
I called Ken one day and said "Ken I need some parts for my ATI prefilters. I don't see them on your website" That NIGHT he managed to put them up and price them, and I was able to buy them immediately. THAT is why I love Ken's Fish! You can't beat the price of sodium thiosulfate either! That's IF you can find it. Thanks guys - you do a fantastic job!
