  • Works as advertised By on 1/13/2017

    Works very well but in my case took almost 4 months for No3 to go from 35ppm to 3ppm
    And Po4 0.00ppm
  • Works Great By on 1/1/2017

    I've been using this for a couple of years now and I must say nothing gives me the peace of mind that my nitrates will be kept in check. I like to feed my fish and corals and have the freedom to do so with the help of Red Sea.
  • works great By on 12/9/2016

    Was skeptical at first until I read some reviews and thought I would give it a try. In about a week was able to lower nitrates from 7 ppm to 0 and phosphate from .42 to 0. I was only going to use this product until my new lid came for my GFO reactor now considering using this full time!
  • worked brilliantly By on 11/23/2016

    I had a persistent difficulty getting nitrates under 5 ppm and SPS started dying and I had cyano problem. I nuked the cyano with chemiclean and started using nopox. AT 12 ml/day I was down to near zero nitrates in a few days (on a 200 gallon tank). I've dialed it into 8 ml/day now and that keeps nitrates at near zero and my coral is doing great.
  • Excellent Product! By on 9/12/2016

    No3Po4-X is an amazing product. For over 5 years I have constantly fought Nitrates and Phosphates. With this product I was able to get my Nitrates down from 20 to under 5 and my Phosphates from over .10 to under .02 in less than a week using Salifert to test. Maintenance dose is at 1ml a day on my 34g tank keeping nitrates stable at about 1ppm and phosphates undetectable with Salifert which im assuming is around .02 or so. Do not overdose this product. If you come back to your tank and you notice white film you have overdosed and need to cut the dose in half and test.

    No3:Po4-X has become an essential item for my reef system. It allows me to feed my fish without the worry of high nitrates.

    dont know about this, worked awesome on my 55 gal tank dosing 12ml a day kept my nitrates at 0, dosed 19 to 30 mils a day on my 125 gal tank nitrates never below 50 and had some clear slime clogging up everything
  • This is the "silver bullet"! By on 5/16/2016

    I have a BioCube 29, in operation successfully for over 4 years. I put every modification on it that it can accommodate: Hydor skimmer, InTank media tower, Innovative Marine bio-pellet reactor, Maxspect LEDs, upgraded Cobalt pump, etc. I have been successfully growing softies and some SPS. I have a montipora plate that has grown from quarter size to 8 inches in diameter. However, for all this time I have been fighting nitrates and phosphates. Nitrates have always been in the range of 12-16 ppm, and phosphates .06-.10. I've carbon dosed with Continuum Microfuel; tried two different brands of bio-pellets; tried several different brands of GFO; have been religious about weekly water changes (about 20%) and changing my Purigen pillow every two months. I finally decided to try NO3:PO4-X, and I'm glad I did! After one week my nitrates dropped to 4 ppm and my phosphates to .02. After the second week my nitrates are at 1 ppm and my phosphates are at 0. I followed the directions carefully. Resist the temptation to overdose. This stuff works where nothing else has, and I could not recommend it more highly.
  • Cautionary Note: Efficient protein skimming is REQUIRED if you use NO3:PO4-X. By on 4/6/2016

    This is a cautionary note to 'reefers' who have not used this product before and who may not typically read instructions thoroughly prior to using a new product. After I received the product I did my usual routine of reading everything that came with it. I found a brief note stating that efficient protein skimming is required in order to maintain appropriate oxygen levels in the water. That is because NO3:PO4-X increases bacterial activity which in turn causes oxygen levels to drop below levels safe for your aquarium inhabitants. Red Sea confirmed to me via Email that this is in fact a requirement, not a recommendation. Since I am one of the minority of 'reefers' who relies upon frequent and consistent water changes instead of skimming I returned the product. All other components of the Red Sea Reef Care Program (RCP) can be used without protein skimming which was also confirmed to me by Red Sea Customer Service.
  • Great Nitrate Reducer By on 3/21/2016

    I always buy the larger quantity as I use it to keep Nitrates down in my 120G Reef Aquarium. You can always tell if I forget a few days as the corals start to suffer. Its great for Nitrates as long as you don't overdose as you will get some stringy growth in your sump and return nozzles. Just follow the dosage daily for your water volume and this stuff works like a charm. It does work better on Nitrates than it does on phosphates but I make my own RODI with 0 TDS at home so phosphates are low anyway.
