Seachem Prime 50mL - Emergency Ammonia Neutralizer for Saltwater Aquariums

Have used this product for years. It works exceptionally well to treat tap water for aquariums. Don’t have to delay putting water in the tank. Just put it in the container and add the water from the tap. By the time you get the container to the aquarium the water is good to add to the tank. Also, a good price from Amazon.

Good for keeping tank clean and fish happy

A few drops worked great. Fresh water compatible!

Works as described! Only need a few drops per gallon. My new betta fish wasn't eating and after testing the water I thought chlorine might be the culprit.Not sure if it was or not, but after a water change that included a few drops, he did indeed liven up and start eating again! Has been doing great since, and I continue to use this for every water change.

My African Drawf Frogs were very unhappy with my water changes. The water was untreated and did not stand long enough to get rid of all of the chlorine. A few drops of this and BOOM. My frogs are happy and enjoying themselves. Excellent product.

Best for water changes - You can't go wrong with Prime

Recommend dose works. I’m not a chemist, but my fish are happy. Low dose, my bottle says two drops per 1US gallon of tap water. I live in SC. Seems two drops are minimal but it works. Was recommended to me by a great tropical fish store, I recommend as well.

Best brand product for using in tap water before adding to your aquarium. I’ve been using this in my axolotls tank for about a year now and have had no issues.
