TESTIMONIALS

"I started my 3000 liter (792 gallon) recifal aquarium about a year ago. For a few months I couldn't lower the nitrate level (30mg/l), so I stopped planting new Corals in the tank. I did not find any satisfactory product in Europe to solve my problem. On the advice of Nosy Bey in Bordeaux, I tested your product AZ-NO3. The result was exceptional! Five weeks after, the nitrate level in the aquarium is close to zero. The Corals are doing very well! I am attaching some photos of the tank and thank you for the effectiveness of your product"

- Olivier D., France

"This product works as advertised. I have a 110 gallon mixed reef nearly 7 years mature and have utilized this product twice. In both cases, the product worked fantastically without any loss of life, cloudy water or any detriments at all."

- Sierra117

"Great product, works as described. Reduced nitrates from 20 to 5ppm in one week! I follow instructions on the bottle, for my tank 350L/92gal. Didn't get cloudy water at all."

- Fadi Al-Sorakjy

"Best Nitrate Eliminator! Love this product. Its the best / easiest way to keep nitrates under control."

Frequently Asked Questions

You have questions.... we have answers.

How Many Gallons Does a Bottle Treat?

A single 125mL bottle will treat between 25 to 30 gallons (100 liters) of marine aquarium water. The 250mL bottle will treat between 50 to 60 gallons (200 liters) of marine aquarium water. The 500mL bottle will treat between 100 to 120 gallons (400 liters) of marine aquarium water.

Zero Nitrates Sounds Great... What do I Need to Get Started?

You will need a marine or reef aquarium with specific gravity of 1.015 or higher, and a fully functional protein skimmer.

Do I need to Stop Using Carbon, Resins or Other Filter Media?

No, you may continue to use as you normally do.

Does AZ-NO3 Work in Freshwater Aquariums or Ponds?

No, this is for Saltwater and Reef Aquariums only.

I've Just Started Using AZ-NO3 and My Aquarium is a Bit Cloudy, Is This Normal?

Yes, this is normal, but not common. Cloudiness may appear upon first usage of this product and can reach peak cloudiness between day 3 - 5 of treatment.

What Can I Do to Treat the Cloudiness?

Regular pre-filter maintenance is required. After day 3 - 5 the cloudiness will go away.

My Fish Have Labored Breathing, What Can I do?

Remain Calm. In RARE cases, if fish show any signs of stress or labored breathing, discontinue use immediately. Iodine supplements are also recommended and additional oxygen sources (ie; airpump and airstone, BioOxygen tablets), may be beneficial.

Is AZ-NO3 All Natural?

Yes! AZ-NO3 is an all natural, non-toxic product that works via cellular respiration.

Does It Really Work?

Yes. Follow the dosing directions as outlined below.

Is This the Same AZ-NO3 That I Used to Buy From Marine Depot?

Yes! This is the EXACT same product! The only change is the artwork on the label and the distribution.
AZ-NO3 is available from www.ASAP-Aquarium.com and select local fish stores and online retailers. (see "Where to Purchase" below)

How do I dose AZ-NO3?

Easy! Follow these steps to get started and you'll see ZERO NITRATES in just 2 weeks!
Directions:

For each 50 to 60 gallons (200 Liters) of seawater, use:

• 2 drops on day 1

• 4 drops on day 2

• 8 drops on day 3

• 16 drops (1.5ml) on day 4

• 32 drops (3ml) on day 5

• 64 drops (5.5ml) on day 6

Thereafter use 8ml (1/4 fl.oz.) per 50-60 gal. daily, until Nitrates are undetectable. Then reduce amount to 4ml for 2 to 4 weeks. You may continue to adjust this maintenance dosage steadily downward by 0.3ml per week to slowly wean the aquarium from the product or to maintain Nitrates at zero.

Test your water for Nitrates every 3 - 4 days when starting treatment and closely monitor Nitrate levels thereafter.
Remember.... you'll need a functioning protein skimmer, but you already knew that!
Go on now and GET RID OF THOSE NITRATES!
