Bought for priming my axolotyl tank; does the job quickly. Use this for my 20 and 40 gallon tanks. I also bring it along to dose friend's tanks when they are just getting into aquariums.

Product was already opened upon inspection. Zero cap or even factory seal. A sticker was stuck across the empty top. Also had carbonation/fizz when opened.

The inside of the bottom smelt sulfuric. It was filled with black specks and had a rotten smell. It smells like rotten eggs from the sulfa.

Buyer beware. Very unhappy with this purchase.

After 12 weeks of use, tank looks the same, worthless. All affected corals were removed from the system and eventually died. It smells like sterile water honestly.
