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.

My experience with Marine Algaefix
This product work well at eliminating the brown diatom algae that I had in the tank. I really couldn't find anything else that would work. I tried trochus snails which did remove some of the brown algae. However, the Algaefix removed it all.
Fast acting
Wow!!! I'm seriously impressed. First treatment and already clearing up the green algae in the water. I got this one so it's safe for snails. It's only been a few hours but the tank is already clear.
It works amazing!!
I don't under why reviewers say it don't work! I had pea soup and within a couple hours it was clear as clear can be so proud of my crystal clear fish tank!
Not so good
I expected it to work better I still have the brown algee
Algaefix for marine tanks
Have been using this a week and already seeing a decrease in the algae. Recommend to anyone with green hair algae growing in their tank.
Product works
Not much to say. I followed the directions and all of the algae was gone in about 5 days. All of the marine life still alive. This is a cold water Long Islan Sound tank. The grand children collect snails, hermit crabs, shrimp, minnows and any sea life they can find and throw them in. I usually get a few severe algae blooms every summer. Happy I found something that takes care of the problem
