API AMMO-LOCK Freshwater and Saltwater Aquarium Ammonia Detoxifier 8-Ounce Bottle (45D)

I've used this for years and it never fails me! Does exactly what it says it should and FAST.

I have had 2 goldfish for about a year now; I am still learning a lot about how to take care of them. One thing I learned the hard way was not to wash filter media in clean water (use tank water instead) - using clean water will crash your nitrogen cycle and cause an ammonia spike. The first (and only) time I made this mistake, I used this product to get those ammonia levels down to 0% in a day; after that, I was able to re-establish the cycle quickly with daily water changes of 25-50% a day and a bottle of beneficial bacteria. Goldfish produce a lot of waste, and this already drives up the ammonia levels. This product has been a lifesaver whenever ammonia levels have spiked in my tank; hoping that I won't face this problem again in my new 125-gallon tank but if I do, I'll be turning to API Ammo Lock.

I always use API products and they continue to not disappoint! I had an ammonia issue in my fresh water tank. Followed the directions and bam, 1st time it worked like a charm and my ammonia is at "0".

This is a dream to use and works great

Received it next day. Perfect. Thank you

Thank you

I got this a few weeks ago, and it came super fast, but the cap was missing, so after I open the bottle I have to seal it with tape. The lack of a measuring device is ok because another item I got has the same measurment cap in a different diameter. It just is sucky that it came with no lid. Great product otherwise

Works great
