“I am 100% satisfied with your nitrate remover. Within a couple of weeks after setup my aquarium nitrates have dropped to virtually zero and remained there.. I’ll never be without one.”Chris

“The filter has been installed for 3+ weeks now. I decided to purchase your filter despite initial skepticism after seeing several critical YouTube reviews. I doubted your zero nitrate claim and figured the best I could hope for was to have the nitrates stabilize at manageable levels. Prior to the Aquaripure I was combating weekly 80ppm nitrate levels with 50% water changes. Starting with a relatively clean tank after week one of using the Aquaripure the nitrates were reduced to 20-40 ppm so I decided to not do a water change and see what would happen. After week two, nitrates where reduced to 20 ppm which is what I anticipated was the best I could expect. I tested the water again today and was shocked to have a ZERO nitrate reading.” – Tom

I am one of your customers that absolutely loves your denitrator system, I currently have a large(purchased two years ago) on my 120 gallon Discus/community tank. I’m looking to purchase an additional unit for a new setup I’m currently putting together, It’s a freshwater 55 gallon that will be moderately stocked with Rams and Cory Cats. I need some advice on picking the right size unit for my application. By the way one of my coworkers recently purchased two units from you after I showed him my setup and raved about your product, then I told him I would never setup a large tank without one of these units.” – Tony

“This would be our third nitrate remover. I would say I definitely notice a difference. In our older 125 reef aquarium, we could not seem to get the nitrate in aquarium below 15-20. We tried a new skimmer, less feeding, weekly water changes, and even mangroves and got very small results. After about 3-4 weeks from the time we got the denitrator, we were at ~0. … The colors on our aquarium coral have improved vastly, especially the Zoo’s. We had some I had forgotten weren’t brown, but now they are bright blue and others bright green.” – Alex

“I got in to African cichlids about 2 years ago. My nitrates will climb 10 ppm/day. Yes, you read that right, without intervention of some type, I needed 2 to 3 water changes (of about 80%) every week. This hobby that I love quickly became unmanageable. I have 2 of the large denitrators. My situation is a challenging one, but the Aquaripure denitrators do the job. My nitrates stay stable at < 10ppm. My fish have never looked healthier. Straight up; Aquaripure has allowed me to remain in this hobby. Thanks!” – Julie

“As promised i said I would contact you about this denitrator, As the weeks have passed and my tank has been cycled I noticed something. I have very little if any nitrates in my tank. I remember cycling my tanks years ago and always notice a high level of nitrates as soon as my tank cycled. Only had your product for 4 weeks and noticed the improved water quality. My danios, guppies and tetras in my 55gal. couldn’t be happier, the only ones mad are my friends. They wondering what I’m doing right. I told them to go with aquaripure’s denitrator, it’s probably the most affective means of removing nitrate in aquarium … Thanks everyone your product really works. First skeptical now I’m convinced.” – Nancy

And although it makes perfect sense I never even thought about how it would positively effect my fish.” – Ann Marie
