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?

Doesn't seem to be working
I have used it every three days since getting it and it hasn't made any difference. I can only add one mL at a time per the instructions and I don't want to harm my fish by adding more. I am also using a UV device designed to clear the water but it's not working either. My next step is to drain the tank and add all new, clear water then treat it and pray the green doesn't come back.
User error
The first 2x I used this, I followed the directions exactly. I didn't really see much of an improvement. Maybe a little but nothing major. During a water change...my husband accidentally tripled the dose! Let's just say I have one very clear fish tank but nothing to look at. It was our fault and not the product but just a warning if anyone gets risky with the dose and thinking they should use more. It most definitely will kill the fish if you aren't careful!
Works Great!
My tank was awful with algae. Tried so many products but this one works! Will not be without it ever.
Doesn’t Work
I have used several doses with no luck with keeping brown algae from returning.
Super clear tank in just a few hours!
Our fish tank started to get super cloudy and greenish/yellow colored and seemed to be getting worse. I ordered algaefix and in just 2 days I recieved it. The tank started clearing up 30 minutes after putting it in. In about 2 hours, my fish tank has never been this clear! My fish seem to be doing great also. I did not clean out the tank or do a water change since my levels were pretty normal despite the algae.
works like a charm!!
our fish tank was so cloudy and green. could barely see our 3 goldfish that we’ve had for 2 years. added the recommended drops of these to my tank and the water is much more clear. i still need to change the water but as i wait for my water pump, i am using this meanwhile!
Keep your pool clean
It keeps the algae in our fish ponds. When we don’t use it we have awful green algae in the water. It’s safe for gold fish too.
Dead/dying fish
Have a 36 gallon bow front, added a little less than 3.5 ml per dosing instructions. Repeated 3 days later with a small water change because some of the fish seemed stressed. Algae started dying...but so did my fish!!! Have been cleaning off dead algae and done two more 30% water changes. Lost 75% of my bottom feeders and 3 top feeders. Will not be using this anymore. Quite saddened. :(
Algae control
The tank looks great & all occupants are healthy. I will continue to use this product.
API Algaefix
I had severe algae bloom after fertilizing aquarium plants, phosphorus level was treated to normal, no improvement, one slightly lower than recommended dose of Algaefix cleared the whole tank and everyone survived.
