This is the real deal with the same sulphur odor, size delivered as described - and about half the cost compared to local retailers.

I lost a Wolf Chiclid - Dovii - Favourite Fish To this chemical - Please follow directions - Sounds

It kill all my bettas and my guppies .

This was a solid deal. I will purchase again. Great product l.

I’ve used this for years and no dead fish.

Great value, just can be hard to figure out dosing for small aquariums.

I have been using this product for years with great results

This is a good product for most fish but they should give a warning about some more delicate such as German rams, couldnt figure out was was killing them until I stopped using this and changed to api quick start

Dans notre cas, un casse tête de moins. Sans ce produit, nous perdions toujours notre eau de l’aquarium. 1 bouchon par semaine et le tour est joué.

Great value for money delivered on time excellent product *****
