SeachemLiquid AmGuard, 500 ml

When ever my Seneye reef reading shows nh3 is 0.028 for example, I use this and in a few hours it always drops back to 0.001 and it stays there. I’m a bit heavy handed when I feed my multiple fish in 300l normal one or two doses (not going to lie I do need to work on that)

I'm a big fan of Seachem products, but what a lot of people don't know, when using Safe, AmGuard, Prime or anything which detoxifies ammonia, your ammonia test will still show ammonia present.This is because tests like API Master Test test for Total Ammonia by raising the pH, which stops the binder working and shows the ammonia as still being high.Get yourself the MultiTest Ammonia (Free & Total) test kit (also Seachem) and it will show you the difference.No, I am not on commission, lol, but I have done a lot of reading and used these products a while. And I can tell the product is working from the behaviour of my fish.If you have an ammonia spike, I would recommend this product, but a lot of the Seachem products detoxify ammonia (Safe, Prime, Neutral Regulator).Just make sure you are not testing Total Ammonia - this will still read a problem! It's the Free Ammonia NH3 which is the toxic version.

This stuff is brilliant in emergencies. Would always recommend.

Amguard did absolutely nothing for my Ammonia levels and at £23.99 you think it would.Extremely disappointed in this product as I am a fan of Seachem's other products - this is the first one I've had any problems with.If you want a product that really works - try Interpets - Ammonia Remover

I liked how little of the product you have to use, and having excellent piece of mind knowing your ammonia isn’t going to spike during a cycle (first set up or accident cycle)

Siempre uso productos de esta marca y este en concreto me ha ayudado bastante con picos de nitritos y problemas en el acuario, desde entonces siempre lo uso en los cambios de agua junto con seachem prime, te ayuda mucho junto con los cambios de agua a reducir y mantener bastante a raya los niveles de amoniaco.

Excellent product. Definitely the best ammonia treatment out there. Why? Because it does not simply reduce ammonia to its less toxic form, like most treatments. AmGuard binds it to neutralize the poisonous effects of ammonia, but still allows your filter's bacteria to utilize it and multiply -- which is the only way to get out of an ammonia crisis. When you reduce ammonia to its less toxic form, not only can your filter not utilize it, but you also increase the pH of your aquarium, which can kill your fish just as easily as ammonia toxicity.

Use this to do emergency Ammonia detoxifying when Ammonia spikes too high for safety. It will only work for about 2 days but gives you that time to solve the problems causing it before it kills your fish. Will also dechlorinate but I frankly recommend Prime for that. I've saved many a tank of fish over the years using this when an Ammonia problem suddenly crops up. Just be aware that this is not to be a permanent solution to overcrowding or overfeeding. I highly recommend having this available for when you'll need it.Essentially, this chemical turns highly toxic NH3 Ammonia to much less toxic NH4 Ammonium.Total Ammonia test kits will show NH4 and NH3 together so your test kit won't likely show any reduction in total Ammonia even though the change from NH3 to NH4 has occurred. If you really want to test ammonia toxicity, get an Ammonia tester that only tests NH3. Those are more accurate anyway at showing toxicity. Most testers tests the total of NH3 and NH4 which isn't really accurate.The bacteria that eats NH3 also eats NH4. So this AmGuard gives you a couple of days that the toxicity is greatly reduced of existing Ammonia so your fish don't die but your bacteria still feed on it. During this time, you should be finding out what caused the high Ammonia (NH3) to fix the problem. Because after a couple of days, any NH4 not consumed by the Nitrogen Cycle bacteria, just changes back to toxic NH3 again.If your tank is dirty or you frequently overfeed or you have a dead fish or snail hidden away somewhere or if you have a lot of plant dye off or if your tank is overstocked, this is likely the cause of your high Ammonia. Not fixing the cause of the Ammonia will just mean more and more Ammonia builds up day by day until either the Nitrifying bacteria catches up and eats it or till your tank inhabitants die. Sometimes the first thing you should do is change about 50% of your tank water and dose Anti-Chlor products and refill with clean water. Then dose AmGuard and Stability (Seachem versions). Prime and AmGuard will have the effect of removing most of the toxicity temporarily and then the Stability will kick start the beneficial bacteria growth you need. Don't just keep dosing chemicals like AmGuard every day. Learn what is causing the Ammonia problem and solve it.Also I can't stress enough that you should have at least a basic understanding of the Nitrogen Cycle that takes place in good seasoned aquariums and how to get yours going BEFORE adding a bunch of fish. Then add fish gradually and manage the increased Ammonia each time before adding more. Also this task will be much easier for you if you use test kits for pH, Ammonia, Nitrites, Nitrates and water hardness. You can literally monitor your water as often as you feel you need to as it goes through the steps of recovery and to watch for possible hazards like Ammonia spikes. Don't assume because you have clear water that everything is perfect. Testing assures you if it is. Liquid tests work better than the strips. Only use the strips for quick checks as they are sometimes not that accurate. You really should invest the money to get a good liquid test kit like APIs master kits.I personally use many of the Seachem products like Prime, AmGuard, Stability, and Pristine to name a few. When properly dosed, they have saved lives of my fish when disasters strike. But you'll need test kits to see where the problem lies. And don't use them all the time as a crutch. Having well-kept tanks with complete Nitrogen Cycles will make the biggest difference in your aquarium creatures survival.

Had an emergency in my tank, ammonia went to 4.0ppm. I used 50 ml of this AmGuard for my 46 Gallon tank over the course of 3 days, not ammonia is below 0.1ppm. Very impressed
