Sodium Thiosulphate 1kg - Aquarium Dechlorinator Photographic Processing

I use this product to de cloronate water in my koi pond. I use 250g per 2 litres of water. Which i mix up in an empty bottle and each water change of about 1000 litres i put a capful in the water.Have also used it on aquariums.

Great for removing chlorine from tap water, something most people with fish ponds need to do. As with all things that relate to fish calculating how much is required is not straightforward, but this bag contains more than enough for a complete water change in any pond I have ever seen. I used 1 ounce for each 100 litres and that did the trick.

Just the job, happy to deal with the seller again

People pay a fortune for pond & aquarium de-chlorinators in fancy bottles and coloured tints, you can create very effective de-chlorinator by simply mixing 130g of crystals in 1ltr of boiling water, mixing well & then leaving it to cool. I recommend reusing old empty branded de-chlorinator bottles to put this mixture in, then when filling with tap water, use this homemade mixture at 10ml per 100gals(uk) and voila! effective de-chlorination for pence not pounds.

Never got round to using it. Seems fair and delivered fast

It's a cheaper way to treat your tank just make sure you do your research and put the correct measurements into the tank, there's plenty to view on YouTube to help you with the correct measurements and advice so you should be ok and can't really go wrong

Bought for photographic use, works as it should.

I use Sodium Thiosulphate in my darkroom to make alkaline based Fixer for 19th Cent technique Salted Paper Prints. I have placed several orders from this company and the turnaround is quick and the quality and price are good
