07-06-2025This bottle is HUGE, much bigger than Id expected (didnt read the description carefully enough I guess!). I have a couple of small tanks (5 gals and 15 gals), and this bottle will last me for years, Im sure.

> 3 dayThis is a great product. I really like the duality of use on it. Depending on the cap size of bottle you bought mine is 50 gallon treatment per 5ml capful, which is very helpful because I do 30% water changes weekly on my 100 gallon aquarium so 1/3 of a cap is more than enough, makes my job simple and will last me almost all year.

> 3 dayThis is my all time favorite water conditioner. It smells awful and works beautifully. I have not had a fish die from a water change after using it.

> 3 dayOne of the best products available to rapidly age water and make safe for tropical fish. Very concentrated - a little bit goes a long way.

> 3 dayThis stuff works fast, doesnt affect the fish if you add directly to aquarium. I have 2 ten gl aquariums, 1 five gl - I use aged tap water (stored in 3 gl water bottles) with 15 drops Prime added when first filled. After two weeks the water still tests perfect except hardness is too high. The fish do not get shocked when I change their water. 250ml (8.5oz) will last me for a very long time.

Greater than one weekI love this stuff. I had some issues when I got my first fancy goldfish (totally a different world from other freshwater fish!) The owner of my local LFS recommended I use Prime, and I cant say I ever plan to use anything else. I used to use APi or Tetra or whatever was on sale at the local box store. Now, if Im brutally honest with myself, Im not sure why I like it so much. You could probably get similar results from the aforementioned brands. But... supposedly this one is better.
