Works for me By Bob E on 10/18/2015

Am using this method w/dosing pump. I had a bad Sal. NO3 test kit and was reading 0. Corals were starting to look bad. So I tried to order new Sal. kit and as usual was on backorder. So I read up and decided to go with a Red Sea test kit as you can replace regeants at lesser cost. Got kit and read at 60ppm. Wow. I knew this would cost a fortune in water changes so I ordered this product and had a spare doser open. Did a few water changes on a weekly basis, and was dosing as the instructions said to. It worked and now I continue dosing at lower dose and will continue to. I have lowered my Alk. as per recommendation and the build up on sides of sump is minimal. The frogspawn has stopped regressing and slowly started to come back. Would have lost them for sure if not found problem when I did. Research says to run at no more than 7.5dkh and I have. It saves me alk dosing to higher levels. Ph is still good. Has good shelf life, is easier to dose than vodka as No3:Po4-X seems to be consistant and is formulated for this purpose. I feed liberally with several large fish in 250gal DT. This system is keeping NO3 to 0-1 ppm and that is great. Have tried sulfur denitrifiers, is hard to regulate, has awful smell, and still have to clean, replace sulfur and spend $ to power pump on that system. Was going to try bio-pellets but the best reactor maker has gone under, so sad(reef dynamics). I test weekly and have not seen higher than 1ppm in 4 mo. THIS STUFF WORKS if used as directed. The large bottle lasts me 11/2 to 2 mo. under $15 a month for 0-1 ppm. Priceless.
Better Than Biopellets By John on 9/27/2015

I had a biopellet reactor for five months and it never controlled nitrates. It took another pump, took up space, had to be cleaned and was a pain. I got rid of it.
I bought a dosing pump and NOPOX and it worked extremely well. You can very precisely bring your nitrates down to near zero. I made a mistake and overdosed and brought my phosphate and nitrate to absolute zero. This caused a bacterial bloom that lasted a few days. It's awesome you can calibrate it to exactly where you want your nitrates. It needs help with phosphates though and I use a small amount of Phosgard.
GREAT!! By Dave on 8/23/2015

I've been using this along with most of the Red Sea Reef Program. It has eliminated my Nitrogen and I can tweak levels for softies when I want. I was skeptical about the phosphates being controlled, but when I ran out of GFS and Phosguard I noticed the Phosphorous dropping to almost imperceptible levels: which is a better indicator of phosphorous levels. Just have to give it time.

This stuff in amazing! Was having an issue with diatoms, and cyano for a long time. I tried all kinds of products/lots of water changes/cleaning this/cleaning that... This is the ONLY thing that has put a stop to it! I highly recommend this to everyone with a reef/fowlr tank.

This is great stuff for carbon dosers out there. Basically a concentrated form of vodka and vinegar. To me it meant dosing smaller amounts and less of an affect on PH that I had otherwise dosing only vinegar. Good stuff at a good price. Careful to not overdose as I currently dose 4ml a day in a 95 total system volume to maintain 0ppm nitrates and .10 phosphates with no GFO.

Having had stubbornly high Nitrates (40-60ppm) months after initial set-up of a 120gal, w/ a 27gal water change each month + using phosphate pads & Chemiblue to reduce / remove No3 / Po4, I ordered this & used just 15ml daily , testing values throughout, & reached zero No3 in13days w/o any water change.
It clearly works & would recommend
Most effective By Steven on 2/6/2015
Steven would recommend this product to a friend
I have tried various ways to keep phosphates under control without ever consistently maintaining a low nutrient tank. This is by far the most effective and easiest I have encountered. I am stili fine tuning the dosage but I am extremely encouraged.
so far so good By Mike on 10/29/2014

My NO3 was 40+ ppm, PO4 was 2.06. Corals were closed and dying, fast. I wanted a liquid "media" so I wouldnt have to use a reactor. I started using this 1 week ago on my 75g reef, softies mostly, some lps. After a week of use, NO3 is now 10 and PO4 is now 1.58 and going down. Great stuff!!! I'm purchasing another bottle to maintain my wifes tank.

Does exactly what it says. I've been using the for 6 months and it keeps my levels in check.

I had been fighting some weird dinoflagellete outbreak for over a year. I had tried everything short of tearing the tank down and starting over. I had done daily water changes and then skipped to doing zero water changes for nearly six months. Yes, my nitrates and phosphates were thru the roof.
I had practically given up and was really ready to ditch the tank and saving up for all new rock...you know I was serious if I'd reached this point. So, after a friend kept pushing me to carbon dose again...and I had done vodka and biopellets in the past...I decided to try a liter of NOPOX.
Well, the bottle is nearly empty at 9mls/day and I can happily say that the dinos are almost completely gone. I'm embarrassed to tell you that my nitrates had risen to over 200ppm and my phosphates were 2.5ppm. I have done one 20 gl water change on my 90gl system since starting the NOPOX. Today the nitrates were at 5ppm. Phosphates are holding at 2.5ppm, but as I understand it from the guide the PO4 will not begin to decline until the NO3 hits zero...so we are getting there.
Now saying all this, I would advise you to be careful with the stuff, know what it is and how it works and preferably stick it on a doser (I use the BRS 1.1ml).
Buy it if you have a good skimmer By Newreef15 on 4/24/2014

If you are going to buy this product make sure you have a high quality skimmer and a high quality test kit for your nitrates and phosphates. It does a really awesome job of keeping my nitrates in check I still have to use some GFO to lower my phosphates but it does a great job of keeping my nitrates under control.

I tried this after changing to the Red Sea test kits. With a large bio load in a large system this is by far the most economical and efficient way for me to my nitrates and phosphates in check.
Fantastic! By Nelson on 4/3/2014

I have tried nearly all forms of carbon dosing for nitrate and phosphate control at one time or another. This is by far my favorite. It is easy to determine your dosing size and starts working fast. Not as cheap as vodka dosing but worked faster for me and is definitely cheaper than multiple large water changes. I have good tank husbandry practices but like to have very low nitrate/phosphate levels for my sps. I primarily use this product only when needed like after a vacation where my mother-in-law was watching the tank. Highly recommended for every reefer from newbie to expert!
Agreed....this stuff works wonders By Justin on 4/1/2014

120G tank with 10-20plus nitrates and water changes couldn't get them down very quick. Algae growth was starting to take over and I knew I had to do something fast.
Read a little about this product...saw all the bad reviews but saw more positive ones. Decided to give it a try and dosed the suggested amount on day 1 for a 120G tank. Stupidly enough I realized that I probably didn't have a 120G worth of water, but more like 80 because of the live rock and sand in the tank. Bacterial bloom overnight, however I did what was recommended by Red Sea in a forum and did an immediate 40G water change. Wont make that mistake again, so a week later I dosed 1/4 of what I should and within a week my Nitrates and Phos are undetectable. I honestly couldn't believe it since I spot feed corals often and feed fish too. I had to get a double take, so I got a different Nitrate and Phos test kit, but got the same undetectable results. I even went out and bought a Hanna Digital Phos, which read the same. Took my water to the LFS, and also the same. Need a good skimmer, change my filter socks every 3 days but I tell you what, this stuff does what it should without any doubt. A+
IGNORE THE HATERS. THIS STUFF IS AMAZING! By Michael on 2/14/2014

I had nitrate problems in my 150 reef for years. I just couldn't get them consistently under 10ppm. I read about N03:P04-X, and since I liked other Red Sea products, I thought I would give it a try. This stuff is like magic. I couldn't believe the results. My nitrates and phosphates disappeared within a week. It's been four months, and I haven't detected nitrates since. A few people on forums here and there talk smack about this stuff, but notice how you can't actually find anyone that says they tried it and it didn't work. Forget about the tools that brag about keeping perfect water chemistry by having fuges and "cryptic zones" <eye roll>...just use a Vertex skimmer, filter socks, and N03:P04-X. I'm not in the hobby to stress about removing nitrates. Don't have a dumb tank. Don't have a dumb life.
