APIPOND AMMO-LOCK Ammonia detoxifier For Pond Water 64-Ounce Bottle

Unfortunately the bio-media in my filter went bad after a year so I had no choice but to swap it out. I wasn’t able to obtain seeded material so my tank ended up crashing and I had to start the cycle again. I bought this to use for my 60-gallon tank so I only need 15mL per dose and it lasts a long time. It takes a couple doses to get ammonia back to zero but it does a great job! I usually have to dose again after 8-12 hours but that’s to be expected until the bacteria can catch up again. I’d recommend this, it works well!

My husband and I have been keeping koi for 7 years. We upgraded over the years, so we now have a 10,000 gallon pond in the back yard. I'm in charge of measuring water quality, using chemicals to treat the pond, and watching the health of the koi. My husband is in charge of the equipment. I have learned you can never rest on your laurels. You need to test your pond regularly. I use API's testing kits. I use many of API's products and have always been happy.When we upgraded, we first got a system off Craigslist (bad idea), and then we were able to save enough to get a really good system. We decided to keep both the old and new system together (bad idea). Everything was fine for a while until we had an ammonia spike bad enough that 3 new koi died before we figured out the problems. Through trial and error and money we discovered had 4 things going on. First, we discovered the system off Craigslit was poorly modified from a pool system (bastard) and built up ammonia. It's probably why he wanted to sell it. Our new system handled the extra load until it couldn't. Second, we didn't realize the water pressure in the pipes to the good system was too high and the clay did not have enough time to do a good cleaning of the water. Third, the pressure was so high the clay was disintegrating, so over time there was more and more ammonia and less and less clay to filter the water. I was at fault because I got lazy about testing the ammonia. I was like how could that much ammonia build up with that much water with that level of fish load and that much filtration, especially as we had never had a problem with ammonia? Whenever I tested for it it was no-existent, until it was so crazy high we were lucky not to lose more koi. We also did water changes regularly. The fourth problem was we did not know that our county started putting ammonia in the water, so every time we did a water change we were adding ammonia back in, even if it was at a lower level. So if you have issues, test your water source as well as your pond.We used massive amounts of ammo-lock until we figured out the problems and corrected them. What ammo lock does is it binds to the ammonia to create a non-lethal version of ammonia. Your pond system still has to get rid of it, but in the meantime it won't be toxic to the fish. It's the next best thing to doing a massive water change (with water that does not have ammonia already in it). When you test your water it will still show as having high ammonia because it does (just in a non-toxic form). I know we would have lost more koi without ammo-lock.So we threw away the bad system, added more piping to decrease the water pressure, added more clay to the filter, added the Cyclone to our system that removes fish waste so less ammonia builds up, and the county started using less ammonia so we don't have to use ammo lock on a regular basis. I test the ammonia regularly no matter what.So, I totally recommend using this product until you can fix whatever the cause of the ammonia is.

We used this for our pond. I like buying i big bottles we have a big pond. I totally recommend it.

My 700 gallon koi pond had a really bad ammonia spike after a filter change that I could not get under control. My koi were lethargic and not eating for weeks. Once I dosed with this product, koi were immediately eating and by the next day returned to their normal selves. Highly recommend!

On the plus side, this stuff stopped my fish deaths from water changes. That's right: brand new dechlorinated tap water was killing them. I finally traced the problem to ammonia, which is a byproduct of chloramine treatment. But some people claim it doesn't work, probably because ammonia is hard to measure accurately. (My own test kit was off my a factor of 10 vs. a machine used by a water test lab that helped find the problem.) So for this reason, people don't necessarily use enough (but of course you don't want to use too much, either). Moreover, the effect is transient, if for no other reason than that fish waste will continue to accumulate. So this a one-shot attempt to solve a dynamic problem, and as such, is only useful in combination with ongoing measurements. My advice for freshwater aquarists is to use tons of plants and biological filtration to keep the ammonia in check; use this stuff in combination with dechlorinator strictly for the purpose of treating the tank just minutes before new tap water comes in. Note that Stress Coat claims to do the work of both, but I prefer separate liquids because, like most aquarists, I have a much bigger ammonia problem than a chlorine problem.

This product works very well. Easy to follow instructions for how much to use - just be sure you know the gallon volume of your pond. Reduces ammonia levels as claimed when used as directed.

The cost and speed of this item was well worth it. Most pet shops do not have this item readily available. Took 24 hrs to receive .

With too many fish this works great in a hurry.

Came in good shape. Will buy again in the future.
