  • Works extremely well By on 10/16/2017

    Follow directions don't overdose and make sure you have a high quality skimmer and this product works extremely well.
  • Awesome Product By on 10/11/2017

    I love this product and my gut feeling is that this works better than Vodka or Vinegar alone. I'm not testing nitrate and phosphate with this, I'm going by visual results and adjusting as needed. The product worked very quickly for me with algae control. I went from having cyano on the sand bed and having to clean the tank glass every day to having crystal clear water, clear sand bed, and haven't touched the glass in a week. This was after about 1 week following the recommended dosage for an SPS tank.
    In hindsight, I would have started with 1/2 dosage and ramped up to the full after a couple weeks because my SPS were not happy with the change in nutrients. The LPS like Chalices, appear unaffected. I feed my fish 3-4 times per day and will start dosing Reef Energy A+B to help the SPS come back to color.
  • as advertised By on 9/11/2017

    The instructions are clear even if the dosing cup is rudimentary. I was warned to watch for over-suppresion of nitrates and phosphates. Red Sea requires weekly testing and dosing adjustments based on results and this had been provided a very soft, gradual transition into better numbers. Instructions state that there is no need for a GFO reactor but I have continued to run one and phosphates have been stable between 0.08 and 0.04. Skimmer is a must, and this is stated in the instruction; the sludge coming out of the skimmer is much darker and disgusting than before dosing. Back to measuring cup.... For the measured nitrates, the instructions stated that the tank needed three cc's per 25 gallons. The tank is a 43 gallon Red Sea Reefer which works out 5.16 mL's, but the measuring cup just ain't close to that good. Which makes me think that the dosing is probably good if its within 20%
  • Smells like hell but works By on 9/9/2017

    By the smell it is clearly denatured alcohol, however, THIS STUFF WORKS. Had a spike in nitrates while I was on honeymoon to nearly 50. in about a month is is down to 5. Having an amazing Skimz skimmer helps too though.
  • Great product By on 3/27/2017

    This product works great I'm very happy with my purchase! But I would recommend dosing half of what it says to dose for your first use.

  • 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.
