In my experience and in the experience of many Aquaripure customers, the Aquaripure is superior in permanently removing nitrates to any live rock/ skimmer/ substrate combo.
The Aquaripure achieves this using anaerobic bacterial processes through which all organic matter entering the filter is completely broken down into their fundamental elements and gasses. See
http://www.aquaripure.com/nitrates.htm for more on that process.
A skimmer just traps larger organic molecules for collection and removal. It does nothing to remove actual nitrates. A lot of rock and a deep sand bed and other methods can all remove some limited nitrates. In a lightly stocked tank you might be able to combine enough other methods to manage nitrates satisfactorily. However, a specialized
nitrate filter like Aquaripure does this in an extremely effective and efficient manner. Most people have trouble getting the results that a specialized nitrate filter can provide, especially tanks with a larger bioload such as fish only tanks. Again, I do not count DIY coil nitrate filters in this category as they are usually ineffective.
There are other valid methods of keeping water quality high and I can not argue against any of them although every method has it's pros and cons. I compare many of them at
http://www.aquaripure.com/Comparison.htm However, the Aquaripure is in my experience and opinion one of the easiest and most cost effective method to maintain high water quality without very frequent water changes.
If an Aquaripure is used and fewer water changes are performed then it is important to continue to monitor all trace elements, pH, phosphate levels, salinity, alkalinity, etc. But regular monitoring and supplement additions are more than enough to keep everything in check and it takes less time and is less expensive than a weekly water changes.
Again, it is perfectly ok if you’d prefer use other methods to maintain your aquarium. My only point is that the Aquaripure is also a perfectly viable option and many Aquaripure customers have found it to be the best option for them. I get new unsolicited e-mails every week thanking me for making my product and that’s what keeps me going.
