The 16 oz bottle is sufficient for a 20 high or low aquarium and it will last a very long time. So far it has proven to be effective as an additive to my tap water to facilitate adding additional water to maintain a constant level of water within my 20 high aquarium. I rated this product as a 4 because I don’t believe any product is a 5 unless it is absolutely OUTSTANDING!

An absolutely Invaluable product. No aquarist should be without it. Does what its supposed to do without any unnecessary bells and whistles.

I have used this water conditioner (dechlorinator) for many years. It is very concentrated so a bottle lasts a long time. It removes chlorine and binds metals, in common with most other dechlorinators. However, the main reason I use this dechlorinator is because it does not contain anything to detoxify ammonia nor to 'promote the slime coat' - I do not like to add anything which I believe to be unnecessary to my aquariums.

I have been using the API Tap Water Conditioner for 11 years since I first started keeping goldfish as pets. I found that the conditioner works like a charm without having to age water first. When I clean the fish tank and add new water from the tap, I pour in 3/4 to 1 capful of conditioner for 40 gallons. I usually do a 80% water change for the goldfish. I know some people say to just do a 25% weekly water change but goldfish are very dirty and it also depends on how many you have. There is enough beneficial bacteria in the filter and decorations and my fish are very healthy and happy. The solution is highly concentrated and a little goes a long ways. I highly recommend this product and use it in conjunction with Stress Zyme and Stress Coat each time I do a water ... MoreI have been using the API Tap Water Conditioner for 11 years since I first started keeping goldfish as pets.

I have been using this in my fish tanks for eight years. I have a Crucian Goldfish (Goldie) & a Common Plecostomus (Tiger) in a 75-gallon tank; both of these fish started out in a 10-gallon tank in 2010..lol...we are really hoping they do not get any bigger. Additionally, we have two small goldfish in a 10-gallon tank that I was given on March 7, 2017 (not quite a year old). API Tap Water Conditioner works pretty well, even for goldfish.
I'm happy my fish got beta flowers and food then floating flower to lotus . This week Fri or Thursday night. Moss balls to.
This product is more concentrated than other brands. You use 10 ml in a 50 gallon tank, where you use 50 ml with other brands. We have 2-50 gallon & 1-125 gallon tanks, so a good product at a good value is important to us.
API water conditioner is a great product which I use every time we top the fish pond up with tap water. Never had a problem with losing any of our fish.
I carefully put this in my tank but was positive it would be okay when I read all the positive reviews, its a different water conditioner than what I normally use ( non super strength). I put in a little bit as directed and a week later two of my bettas died. They were fine before I started using this product. I dont even want to try using this on my other tanks. Beware.
My first aquarium! I bought a great one that has the requited separate tanks for my 3 Beta fish. Lots of joy from watching them! I definitely needed to condition my tank water for them.This is a great buy and value! Point being, my fish are happily swimming around safely!
