Sodium Thiosulphate 500g - Aquarium Dechlorinator Photographic Processing

Works a a lot cheaper than liquid pond dechlorinator

Good at removing Cl from main water. Used for pond, very little amount needed so size sold will be good for many thousands of litters.

Brilliant, just what i jeeded and the science trick went really well, it turned a jug of water and iodine back to just clear water again!

Saves on expensive declorinaters

Works well. Seems good quality.

After watching YouTube I decided to get this product best thing I did it save you loads of money 💰

I use this because the tap water in Ireland is so full of chlorine that i couldn't drink it. Some research showed that this is good for the fish and aquariums and non-toxic for humans. So I tried and I'm thrilled how wonderfully that works. I recommend it.

I wanted this to use as a dechlorinator when changing water in fish tanks. The chemical supplied does the job however a few printed instructions on quantities to pre-mix before use would be helpful. You cant just dump the lot in and hope, you need to pre-mix a concentrate and then add it dependent on how many litres or gallons you of water you are changing. Same for ponds. Without a suggested guide its a bit of a pain finding out the info.
