    Ammo-lock works

    By Ammolock on Mar 2, 2021

    There isn't a lot to say about an aquarium additive but it works as it should at a fair price.

    I was having an ammonia spike in my new 36 gallon aquarium according to my local fish shop. Used this product when I did a water change.

Have since cleaned the 36 gallon and starting over. Apparently the ammonia is in my tap water. Called another fish store & was informed the ammonia will always test positive since it’s in my tap water, but as long as I use prime my fish will be fine as prime neutralizes the ammonia.

    I think it’s works.

    By on

    I think this works but hard to tell because ammonia will always read the same even if it is working. Fish are still alive.

    Leads to more Cleaning

    By on

    Made the water so unbelievably cloudy after just one dose, I had to completely change out the water again after we just cleaned it. Don’t recommend!!

    Kept my fish alive!

    Without thus product a lot of my fish would have died. I am new to the hobby and my ammonia levels were out of control. This product saved my fish!

    Great But Makes Water Cloudy

    By on

    I recently had an ammonia spike and this helped out very much just be careful this does not remove ammonia it detoxifies it. It also makes your water cloudy but it's not that visible.

    It's Great

    By on

    Some of the people here will mention how it makes you water cloudy, but that is usually because you added too much. Another reason this can happen is if you don't have enough water circulation and you need to stir it around a bit. I love it though, I have only had it cloud up on me once when I was using it with a betta with a low flow filter. It's easy to use and really helps with the ammonia.

    Decades of experience. Happy customer.

    Started up a new tank after taking time off to deal with health & family issues. Of course I got new tank syndrome... As long as you use the right additional supportive products in tandem with the Ammo Lock it works perfectly. I don't even get cloudiness. EVER. If there it's a tinge of the water not being perfectly clear that's usually from the other things I'm adding with it & it all goes away immediately. Be wise with your dosing. Forexample, if you are dosing for a 10 gallon tank, don't measure exactly for 10 gallons of water... Subtract your rock, decorations... Everything that takes up space and you'll probably only need to dose for 7 gallons.

My fish started to get ill from the ammonia and within 24 hours I noticed a huge difference in their health. It made it so that I didn't need to add even more chemicals to treat illnesses. Get a REALLY good live bacteria (or two) and use the Ammo Lock every two days. Test your PH & Ammonia every single day. Do water changes accordingly. Push that bacteria, oxygen and filtration... Someone said raise you're temp to 85°... I DO NOT recommend doing that while your ammonia is high. The higher the temperature the more toxic the ammonia is. Once you have your ammonia in check you can safely raise it. But … more

    Works like it's supposed to.

    By on

    I use this every time I do water changes for my 20 gallon and 55 gallon tanks. It works instantly and my fish and snails are able to adapt quickly. I do not have the best results when using API's Quick Start solution on its own - and usually I'll always have to add Ammo-Lock along with it. However, the Ammo-Lock Detoxifier works great on it's own and personally I do not recommend adding another solution unless it's API Stress Coat (which helps repair a fish's slime coat). I have not encountered the cloudy water problem that others have mentioned, it usually disperses quickly in the tank and clears out.

    Cloudy water

    By on

    Not sure if it detoxified the ammonia but the water is so cloudy now and I can’t get it to clear. I have to empty all the water and refill the tank. Ugh
