I use it when we add new animals to our tanks, when we do a big Aquascaping change which causes stress because I am in the tank for an extended period of time or when I see an animal in our tanks has a scrape or abrasion. It has cut way down on trips to our quarantine tanks for both our saltwater and freshwater fish. It is an excellent product.
African Cichlids looks happy, Nerite Snails look happy, Bristlenose Plecos looks happy, & plants look happy. No Complaints.

Mostly use this for my small outdoor ponds with high fin platys and the other with golden shiners, but also indoor fish tanks too. Works great and you don't use very much with water changes! Have been using this product for years so was glad to see Aquarium Co-Op got it in! Thank you Cory!!!
Not only do I use this for declorinating water, but when adding new fish. Also is useful to heal fish after your tank faces something like ich.
I've been using this stuff for ever now and simply because that's what my dad used. I use it to add water during water changes and so far my fish haven't been killed. It works but nothing amazing or game changing happens.
