About API Water Conditioners

It’s Smart To Be Proactive!

The best way to keep your aquarium clean is to maintain good water quality. This will help keep your fish strong and vibrant and prevent disease. Water conditioners and test kits from API can help you keep your aquarium water safe and healthy.

How Do I Maintain a Healthy Environment?

It is important to test your aquarium water weekly to ensure it stays healthy for your fish.  In addition, a bi-weekly partial water change of no more than 25% will help reduce toxic buildup, remove debris the filter missed, and replenish the oxygen available to your fish.

Feed Twice Daily and Test Water Weekly

Feed your fish twice a day, check their water temperature, and observe them to make sure they are active. You should also test water quality weekly for optimal safety. For fish to thrive, their water must closely match that of their natural environment—poor water quality can cause stress, illness and even fish loss. The 6 important parameters for healthy aquarium water are ammonia, nitrite, nitrate, pH and water hardness (GH & KH). All of these can vary over time and are invisible to the eye.

Change Water and Restore the Ecosystem

In a closed aquarium environment, there are no natural rivers or streams to carry away debris and other waste materials. That is why you should replace 25% of your aquarium water every two weeks, making sure to add water conditioner to your tap water to make it safe for your fish. You should also change your filter media and clean your gravel monthly. Adding beneficial nitrifying bacteria with API Quick Start when you do will help restore your aquarium’s fragile ecosystem and avoid disruption.

What Do API Products Do and When Do I Use Them?

API Test Kits

Use test kits weekly to monitor water quality parameters, which can vary over time and impact the health of your fish.

API Stress Zyme

Using this every week will help keep your aquarium clean and your gravel and ornaments sludge-free.

API Algaefix

Use weekly to control algae growth and keep aquarium glass, ornaments and plants clean.

API Stress Coat

Use every 2 weeks during water changes to make tap water safe, and when adding fish, or when fish are injured.

Do not recommend

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. When I got home from work the next day, my tank was so cloudy & all my fish were at the top gasping for air. 2 of my neons did not make it, so I transferred the survivors to my 10 gallon tank. 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. Fish have been doing fine ever since. Will not use the remaining bottle of this product.

Ammo-lock works

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

I think it’s works.

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

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!!

Great But Makes Water Cloudy

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.

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!

It's Great

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. Make sure you're using it as directed, every two days while you're ammonia is spiked. 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

Works like it's supposed to.

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

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
