## Description

API POND AMMO-LOCK Ammonia detoxifier For Pond Water 16-Ounce Bottle

Review: Works in Tanks Too! - 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!
Review: Ammo-Lock works - 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.

## Questions & Answers

**Q: I used it for my pond 1 week ago. The ammonia value is from 0.25 to 1.00，Today, the ammonia is 4.00 Is this normal?**
A: Ammo lock will not reduce the ammonia levels, however, it does make the ammonia non-toxic when used. Your current ammonia level of 4.00 is extremely high, which can compromise the immune system of your fish due to high stress levels caused by the ammonia levels in your pond. Kindly note your fish should only be fed once to twice a day in small increments and must be consumed within the first 5 minutes or less, left over food will cause an increase in ammonia levels as well as run off after a rainstorm. Please be sure your filteration is sufficient for the quantity of fish as well as the pond capacity, bio balls should be implemented in your filteration system since they will capture the bacteria. Hope this helps and good luck :)

**Q: Since high phosphate and ammonia levels cause green water, will using Ammo-Lock clear cloudy pond water caused by excess fish waste?**
A: I use this mainly for the high ammonia in our water , and of course fish waste . I also vacuum to get rid of the waste. I don't think it will clear the water , I use a filter system for that .

**Q: Is this product still usable if it freezes ?**
A: Thanks for your question. The bottle doesn't have any details about storage conditions, usually this means a product will still work as intended if stored in very hot or very cold settings. I left a voicemail with the manufacturer to get confirmation on this. If you need anymore help you can call Pond & Garden Depot toll free at 1-866-305-5459

**Q: How long will ammonia be reduced after use?**
A: Ammo-lock detoxifies the ammonia to ammonium, it does not remove ammonia.
