Microtroniks QUALI-TECH Sodium Thiosulphate 99% (500 gms) Na2S2O3 CAS: 7772-98-7

Quality wise perfect. The packaging though needs improvement since it involves chemicals. Labelling is sloppy as well. Giving it a four stars because of the product.

Useful in vet poisoning case..

Good product

Good one. Good for aquarium use. Fishes be stable once you add this in water and kills the clorine from water
