SeachemPrime 50mL - Emergency Ammonia Neutralizer for Saltwater Aquariums

Using this during a fish-in cycle and the fish are thriving, so it must be working. I add this during my currently daily water changes.

Saved my betta tank. Small natural tanks are so hard to keep in cycle. I was struggling with amonia and doing every other day water changes trying to get it in check. Nothing was working. After reading reviews on many solutions, I decided to give Prime a try. Within a week, my water was perfect and I've had no issues since. This stuff is great! 2 drops per gallon is all it takes.

I've been using Prime for the entirety of my fishkeeping career.I prefer to buy a larger bottle and continuously refill these 50 mL bottles. That way, I typically dose two drops per gallon of water and this also seems to lessen the sulfur smell that is notorious to Prime. I also have an aquarium in my office at work, so I just transport the small bottles between home and work when the bottle at work needs a refill.After a few years the flip cap broke on one of the bottles, but I think that's pretty reasonable for the timeframe.

Seachem Prime is a must-have for any aquarium owner. It effectively removes chlorine, chloramine, and detoxifies ammonia, keeping my fish safe during water changes. I’ve used it for years, and it always works perfectly—highly recommended!

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.

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.

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 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.
