API AMMO-LOCK Freshwater and Saltwater Aquarium Ammonia Detoxifier 473 ml Bottle,473 ml (Pack of 1)

Even running a tight cleaning regime in my tank, I still have odd ammonia spikes for no obvious reason. This works perfect every time, and relives the worry about my fishes health.

Got this after trying other products that say they help control Ammonia but to no effect. However API Ammo Lock actually worked after just 3 treatments, very impressed with this product.

Bought to deal with an ammonia spike. Works as intended and converts the ammonia to its non toxic form for 48hrs. Easy to use and measure out.It’s worth noting that if you are using the API ammonia test, the non toxic form of ammonia still shows up as the test looks for both NH3 & NH4. So you could be fooled into thinking this product isn’t working.I used a Seachem Ammonia Alert (which only tests for the toxic form NH3) to keep an eye on when this product was wearing off.Only issue is the bottle dosnt last very long, as it’s not a concentrated solution so if you have a prolonged ammonia issue as I did (my cycle crashed after medication) you will run out.

Great

Well I didn't want to use chemicals too much but had a bad ammonia spike, so I followed the instructions and treated my aquarium, the Seachem alert said ammonia level is safe but the liquid API test showed higher ammonia, apparently this is how it should be as the Ammo Lock converts the bad ammonia to good ammonia which does not harm your fish, it seems to work for me so in an emergency I can recommend this product.

This product saved the lives of my fish. My goldfish decided to have some children which overloaded my pond filter and water cleansing system. Ordered a submersible pump for water change with hose for water changing, but it takes a long time to receive delivery of bulky items like a submersible pump and time is required for setup. Adding this chemical was a fast emergency solution for the extra chemicals generated by a suddenly overpopulated pond. No fish were killed due to Amazon's fast delivery of this item.

It does what it says

I have used this for almost a week now & I am always reading 0.25 ppm Ammonia using the API water test kit, I'd like to see some proof that it converts Ammonia to less a toxic substance, if that's the case no Ammonia would be present as it has been 'converted'. To be honest I feel it has very little effect on the Ammonia what so ever & is like a humans placebo. I have tap water that reads lees than 0.25ppm, at a guess I'd say 12ppm & I add 5ml per 20-30ltr during a water change - which has little effect as I still read 0.25ppm Ammonia regardless how many water changes I do my readings are as follows - Ammo 0.25ppm, Nitrite 0ppm, Nitrate 20ppm. I also use Tetra Ph/Kh minus which states adding 25ml to the aquarium 'will instantly remove Ammonia' up to 4.0ppm.....it doesn't, all it does is lower the Ph sharply which in turn in combination with the 0.25ppm Ammo stresses the fish even more!!
