NITEH08 Nite-Out II Aquarium and Fish Tank Cleaner for Rapid Ammonia and Nitrite Reduction, Freshwater and Saltwater, 8 Ounces

Works as advertised. Tank looks better after treatment.

I finally got my planted tank up and running and began the cycling process. My wife and kids did not understand that it would take a couple weeks and went out and got a couple fish and some pretty pricey but beautiful shrimp. Well you probably know what happened, watched the shrimp die every day. 50% water changes didn't help, bioload was too great. With all the shrimp gone and my kids' fish trying to cling to life I looked for a solution. Half the forums and posts and subreddits I visited recommended nite out. I figured the price was worth it if it works and the bottle would last forever anyway. So I started using it and continued my 25% water changes. Everything stabilized in less than a week. Now would you believe my wife needed to have a dwarf puffer? And that puffer was a terror to my kids fish? And I had to go out and buy another tank just for that tiny fish? Well those things happened. I learned from my mistakes and used nite out from the beginning along with stuffing my old filter into the new tank's pump. Now we've got two tanks running smoothly.

I was having nitrite readings of .25 ppm and nothing was helping, after a couple weeks of daily water changes with that reading always coming back the next day I was desperate to get that trace amount of nitrite gone. Used this yesterday after a water change and I’m happy to report after testing today nitrites are down to 0ppm!! If you are having a similar issue I highly recommend this stuff combined with their special blend, works like a charm!

It works. I placed the correct amount in the water and left the UV light off for 24 hrs. Definitely buying again. Ammonia is something I fight weekly because of my turtle and fish. I highly recommend this product.

This stuff stinks like you wouldn't believe. I recommend you mix it with water outside and then pour it in the tank. Stunk my house up for hours, but the smell doesn't linger in the water. If you mix it with water outside and then pour it in your aquarium it will do wonders for the overall health of the aquarium and fish without the smell of death in your home for hours.

The media could not be loaded. Before getting my betta fish I cycled the tank (as all must do) and it was stuck in the high nitrite and nitrate phase for so long so I bought this to see if it would work. I added it daily for about four days and boom! 0ppm for ammonia, nitrite and nitrate! I now use it as maintenance for every water change! It’s also super affordable compared to other bottled bacteria. 10/10 recommend.

works great, nitrates went down in like two maybe three days.

I decided to bring my fish tank back to life but I forgot about the cycling process. I bought this and within 24hours I saw a major change.
