Used this product for years. A bit disappointed I couldn't get it in a gallon size. But always on inventory in my house and use it when i do a water change in the aquariums at about half dose. Vital for new aquarium setups to get established!

I gave it three stars because of the price. I love this product it does a great job, But do the math If you buy 4-16 oz bottles it is $4.54 cent cheaper then buying this 64 oz bottle. You would think buying it in bulk you would get it a little cheaper but instead they rip you off for $4.54. And they will keep doing it as long as people keep buying the 64 oz at this price. All I am saying if you want to save money think before you buy.
