Save Time and Money, Eliminate Nitrates, Control Algae, and Reduce Maintenance!

An Aquaripure Nitrate Removal Filter will greatly reduce the need for water changes in your fish tanks, saving you time, money, and reducing the stress on your aquarium fish.

What is an Aquaripure Nitrate Removal Filter?

The Aquaripure Nitrate Removal Filter, also known as a denitrator, is a comprehensive biological filter which will completely remove all organic matter and nitrates in an Aquarium. This type of filter is also known as a denitrifier, biodenitrator, anaerobic biological filter, nitrate reactor, or simply a nitrate filter. Other biological filters only convert organic matter into nitrates which then accumulate in the aquarium, physical filters only remove larger particulate matter, and skimmers do not remove any nitrates. The Aquaripure nitrate removal filter (or denitrator) uses beneficial bacteria to break down invisible organic matter and nitrates completely into Nitrogen gas which then escapes into the atmosphere. This same process is even used by some water treatment plants to make wastewater safe for human consumption and to clean polluted water. The Aquaripure nitrate removal filter does this in an extremely safe and controlled environment and after the water from the Aquaripure denitrator is aerated there is nothing left but pure, clean, crystal clear water.  Don’t just take our word for it, read some of our customers actual testimonials.

Can I use it with fresh and saltwater fish tanks?

YES! The Aquaripure nitrate removal filter (denitrator) can be used with all freshwater tropical fish aquariums and saltwater aquariums including coral reef tanks and freshwater planted tanks. It is completely harmless to all freshwater and marine aquarium fish. All any aquarium really needs for great water quality is good water flow, a little mechanical filtration, and an Aquaripure denitrator.

How can an Aquaripure Nitrate Removal Filter save me money?

The Aquaripure denitrator will greatly reduce water changes. As an example lets use a 29 gallon freshwater planted tank and a 180 gallon saltwater reef tank. For the freshwater planted tank, if your tap water is hard or alkaline then it shouldn’t be used for water changes and you would have to buy distilled water (that has pH of 7) for about $1 a gallon. It would take at least 30 minutes a week for a 35% water change on the FW tank if weekly water changes were kept up. On the saltwater reef tank you would have to use salt which costs at least $0.35 a gallon and that’s just using plain old tap water. If you use R/O water the costs go up a lot more. The saltwater tank would take at least 2 hours total to mix drain and refill and get everything back where it was with a 35% water change.

So … If you did a 35% weekly water change on both tanks it would take 120+ hours per year. Even at minimum wage that would be at least worth $800+. The freshwater tank would cost (29 x .35 x 52 x $1) = $528 in distilled water and the saltwater tank would cost (180 x .35 x 52 x $0.35) = $1147 in salt. So the total cost would be at least $2475 a year. With an Aquaripure nitrate removal filter (denitrator) you could only do water change about once every 3 months so that’s a savings of well over $2150 every year!

What makes Aquaripure Denitrator Filters the best?

Don’t be fooled by the cheap nitrate removal products or denitrators. These are simply a tiny band-aid on a large and permanent problem. You will need to buy them or their internal media over and over again and they are not a good value. Only a specialized nitrate filter like Aquaripure nitrate removal filter (denitrator) can provide permanent and complete nitrate reduction. And unlike other similar nitrate filters, Aquaripure Nitrate Removal filters use proprietary and patent pending technology to maximize it’s efficiency and effectiveness.  Aquaripure denitrators all have a tremendous internal surface area for denitrifying bacteria to grow and thrive, much more than any “coil” denitrator or the other competition. For example, it would take more than ten “coil” type denitrator filters to equal the nitrate removal power of a Large Aquaripure denitrator. Moreover, many of the other denitrator / nitrate removal  filters are vastly overrated in terms of their capacity.

In “sulfur” denitrator nitrate removal filters, the effluent contains large amounts of H2SO4, sulfuric acid, and SO4, sulfate. You must have a separate reactor with carbonate to neutralize the acid. Also, the costly sulfur and carbonate media must periodically be replaced. None of this is an issue with Aquaripure nitrate removal filters (denitrators). With Aquaripure denitrators, no sulfuric acid or sulfates are produced and nothing will ever need to be replaced.

Aquaripure nitrate removal filters utilize the only highest quality tubing, valves, and connections. You will not find any cheap parts on an Aquaripure denitrator.  Aquaripure nitrate removal filters are also “pre-populated” with more beneficial bacteria than ever to start working fast. Unlike other nitrate removal products, the Aquaripure nitrate removal filter (or denitrator) is designed to be safe, extremely easy to use, require little maintenance, and completely remove nitrates for many, many years. Here is a more in depth product comparison.

Why is Nitrate removal so important?

All animals including fish produce ammonia and other organic waste products which are turned into nitrites and then nitrates by bacteria. The fact is that in any mature aquarium high nitrates are the primary reason to do frequent water changes. Nitrates are less toxic than ammonia or nitrites, but they are still toxic to humans, animals and fish and are a primary cause of water pollution. For example, the US Environmental Protection Agency’s maximum allowable nitrates in tap water is only 10 parts per million. Nitrates are also the primary cause of unwanted algae growth in an aquarium. Here is a more advanced discussion on the topic of nitrates.

How big are Aquaripure’s denitrators?

The Mini Aquaripure denitrator is 4 1/2″ x 6 1/2″ x 12″.  The Small Aquaripure denitrator is 7 1/4″ x 9 3/4″ x 14 1/2″.  The Medium Aquaripure denitrator is 7 1/4″ x 9 3/4″ x 24 1/2″. The Large Aquaripure denitrator is 7 1/4″ x 17 1/4″ x 24 1/2″. They can be easily be hidden underneath or behind almost any tank setup.

Do I have to change anything or add anything to the Aquaripure Nitrate Filter?

Unlike other filters in which you have to replace the internal media, you will never have to change anything on the Aquaripure nitrate removal filter (denitrator). There are no filters to change and no mess to deal with. There is a “feeding” tube on all of Aquaripure’s nitrate removal filters (except the Mini) that is very easy to use. You simply inject sugar water or alcohol into the Aquaripure denitrator once a week. Feeding and adjusting the Aquaripure denitrator only costs pennies and will only take seconds of your time. Aquaripure’s denitrators are designed to be easy to setup and maintain, and will give you many years of service.
