- NO3:PO4-X Nitrate & Phosphate Reducer - Red Sea
Prevent algae breakouts by removing the nitrates and phosphates in your reef tank. NO3:PO4-X Nitrate & Phosphate Reducer from Red Sea is a complex of carbons each with a different strain of microorganisms in a reef ready solution.
Three Sizes Available
Red Sea's NO3:PO4-x is a part of their Algae Management Program that combines highly effective, controlled biological reduction of nitrates and phosphates for all reef and marine aquariums. Between testing and dosing the proper additives, nutrients in the aquarium can be easily managed with no undesirable effects. NO3:PO4-x helps promote naturally occurring nutrient-reducing bacteria that already exist in your aquarium.
- Reduces and maintains NO3 and PO4
- Cost Effective
- 100% Reef Safe (do not overdose)
- Nitrate and Phosphate reduction in a controlled setting
We highly recommend starting with half the recommended dose for your aquarium type and using high-quality Nitrate and Phosphate test kits during implementation. Keeping a steady dosing regime is key, and daily dosing is highly encouraged. We prefer to use a dosing pump system for daily dosing, which keeps the doses very precise and reliable.

UPDATE OF EARLIER REVIEW By Bob E on 5/9/2020Bob E would recommend this product to a friendI have been using this method for de-nitration for almost 5 yrs. it has worked great for me. When I first started using it I was getting the white gunk but after getting it dialed in with my doser, the gunk started going away. It seems as if you need to monitor the nitrates and bring them down slowly, Dosing pump is the best way to use this. If I let the nitrates raise a little to say 2-3 ppm, I increase the doser very slight for 2 days and then back to my normal setting. I never need to alter my doser setting but very little. I like nitrates at about 1-2 ppm. My 250 gal DT has been up and running since 12- 2006. I tried 3 different types, scrubber, sulfur and frequent water changes and this is the best yet. I do water changes every other month, yes 2 months. 2 large sps - 5 lps -and many softies. 12 fish with 3 large tangs. I have saved boat loads of salt. I save about $400 per year on salt and spend about $150 per year on NOPO. My tank is happy, I'm happy and spending less on salt makes my wife happy. I dose Alk, Cal & Mag with BRS pharma. I have a Spectra pure doser for the NOPO and it has been very reliable. Calibrate it once a year and it doesn't change any settings, it's spot on. I dose the ACM with an old Aqua medic 3 gang that just won't quit. I don't want to dose with WIFI or rely on my Apex for that. I test weekly and make any adjustments with the 3 part manually. This NOPO would give me 0 at all times if I wanted it to, but running this tank 1-1.5 ppm is good.
THIS STUFF WORKS, PERIOD.
This product saved my tank By David on 7/9/2019David would recommend this product to a friendI had a terrible problem with a very stubborn outbreak of green hair algae. My tank was even being maintained by a professional. It was obvious that my levels were out of control even though they tested very well. I tried turning lights out, reducing feeding frequency, and increasing water flow, but the algae kept spreading. I lost approximately 75% of all my coral, and almost any part of my tank that you could see was covered in green hair algae. I found this product and had decided that this was my last attempt to save my tank and if it didn't work I was going to start over. I started at the recommended high dose and following other directions to the letter. After a few days I noticed some of the algae changing color and becoming slightly stringy. Being a little desperate i upped the dosage and started noticing a while filmy look to the water. I recognized that this was a sign of overdosing so I backed off to the recommended amounts. Every day I saw more and more algae changing color and breaking off the rock into the water column and into my filters. Before the first bottle was used, there was virtually no sign of green hair algae in my tank AT ALL. Now several months later I have the healthiest tank Ive ever had. I now use this product if I ever feel like I over feed, or if a fish/invert, etc dies and I worry that my levels will spike. I absolutely cannot stress enough how well this product did exactly what is said it would do. It literally saved me thousands of dollars in starting over. Please try this if you are fed up with other methods and think nothing will work, This product will save your tank.
Amazing for Nutrient Control By Dmize on 1/1/2019Dmize would recommend this product to a friendThis product is amazing for nutrient control. Probably hands down the best product I use for my 150g mixed reef tank. In conjunction with my skimmer and bio-pellets my nutrient levels Phosphate and nitrate are rock solid. I used this to counter an out of control algae bloom and it did wonders with the 3 day black out method.
Great Nutrient Control By Jeff on 11/11/2018Jeff would recommend this product to a friendAwesome product once you get to know it. I made the mistake by not letting my aquarium cycle and started using nopox to get my numbers down. using the recommended dose i got bad slime and a major dino outbreak. I stopped nopox raised my nitrates back to 80 with sodium nitrate then when dinos and slime stopped and my tank was cycled i only dosed 6ml for my 120 for 1 month and now my phosphate is steady at .06 and nitrate is at 1 and finally I cut back my dose to 2ml per day with heavy tank feedings, my tank has never looked better. word of caution is to use way under the recommended dose and start slow. also a great idea to dose red sea energy a and b to keep those coral colors. now that i know how to use this i love it very simple.
Works wonders By Joe on 7/2/2018Joe would recommend this product to a friendIt kills/hinders the growth of algae as advertised. Dosing 5ml on my 210 since 10ml seemed to stress out a lot of my corals. Within two weeks most if not all of the algae in my tank was gone.
Does what it says, and no adverse side effects By Matthew on 4/16/2018Matthew would recommend this product to a friendI had a massive algae outbreak in a very new tank with only a few things in it. I moved as much livestock as I could to my already very established additional tank, and begin dosing this. Within 2 weeks, my NO3 had dropped, and the algae has cleared up significantly.
best silent/ulm method of no3+po4 reduction By overclockwise on 3/28/2018overclockwise would recommend this product to a friendI have my tank in my bedroom so silence is a must. I've looked into chaeto reactors, biopellets and refugiums - they all had one thing in common, noise from something running 24/7, increased maintenance or spending $$$ on a light that will be on while I'm sleeping. I already dose 2 part through a doser so I got this instead. It doses 4ml at 1PM everyday and that's it. No pump noise, no reactors to clean, no cheato to harvest, no large refugium taking space, and no extra light in the room. I will keep buying until Red Sea stops making this.
Works when others won't By Brian on 2/9/2018Brian would recommend this product to a friendI had high phosphates from an unknown source and I tried everything to get them down but nothing worked. I tried Rowaphos, ALR 99, GFO, Phosguard, etc but this is the only product that helped me. I add about 2ml once a week now to my Reefer 250 and I never have phosphates or nitrates.
Stuff just works great on my SPS reef tanks. By buntaro on 12/12/2017buntaro would recommend this product to a friendI used to use Purigen, carbon, bio-pellet reactor, Chemi-Pure Blue and just about everything else, with frequent water changes, and ALWAYS was fighting NO3/PO4 issues. Got this stuff (which sells like nail polish remover BTW) and I've cut out all other additives and have absolute great water parameters. I wish I would have started using it earlier, had it, opened the bottle and thought "I'm not putting acetone in my tank!", but finally did and it works wonders. Love the stuff and sooo much less hassle and cost than a bunch of other expensive measures that just don't work very well.
May take a little bit to get dialed in By John on 11/28/2017John would recommend this product to a friendThis is a great product and is super easy to dose daily on my 60 gal system. It did take a bit to get my system balance, as I had a phosphate imbalance in my system. I added GFO, even though it says not to, to bring the nitrate/phosphate balance inline. Now that the system is stable, I don't even bother testing for nitrates/phosphates anymore.
no3 nopox By lisa on 10/24/2017lisa would recommend this product to a friendthis is the best carbon product for your money
Works extremely well By richard on 10/16/2017richard would recommend this product to a friendFollow directions don't overdose and make sure you have a high quality skimmer and this product works extremely well.
I really appreciate BRS, all the videos are so helpful. You put in so much work in the BRS 52 weeks and Investigates My tank in a 33 gal cube with all HOB equipment. I have a good skimmer and I only have 7 small fish. I was feeding 2 sun corals and this is when my NO3 went up to as high as 100. and the p04 to .2 I started using Rowaphos and vodka dosing. My p04 in now .03. N03 is still 25-50. Will NOPOX do a faster job of lowering my nitrates? I've been using vodka since 8/11. My currant dose is 3,7ml/day. Thank you
Thanks for getting in touch with us in regards to lowering your nutrients with NOPOX. I am not sure if this would lower it quicker, but I personally would feel it to be more of a stable additive then vodka as its made specifically for aquarium use. I have although seen a few tanks maintained with vodka with amazing results. Please let me know if there is anything else that we can assist with. Thanks!
If my tank is running very low to 0 nitrate and phosphates is this still recomended if I want to build benificial bacteria like the product claims?
You will not need to use this product if your levels are undetectable. While this provides food for bacteria it will most likely result in over dosing and issues such as excess bacteria such as Cyano.
While using NOPOX can i still run my U/V sterilizer?
Typically with Bacteria growth systems such as NoPox, Zeovit, and Bio-pellets it is not recommended to run UV sterilizers as they can keep the bacteria from repopulating in the tank as needed! Feel free to let us know if you have any further questions!
If all is reading well is this safe to use daily! Just to keep all under control
This is recommended for daily use for keeping up with nitrate levels. Feel free to let us know if you have any further questions!
I have a 10 gallon reef tank. How much of this product would I use in my tank or would it be too much for my tank?
You will use 2ml per 25 gallons of water.
Can I use Red Seas No3PO4x added in with my ATO/Kalk? I make up a weeks worth at a time. I'm away from home frequetly so the daily measure and addition of the liquid is not possible.
It may be possible however you would need to perform some math by seeing how much Top Off water you add each day. We do not recommend this as the nopox will settle out in the RO water and not be mixed evenly. Feel free to let us know if you have any further questions!
Hi I was wondering if this product expires or gets old and breaks down? Trying to determine what size bottle to get because I have a smaller tank and it last so long I dont want it to go bad before I can use it up, thanks
As long as you keep it well sealed and away from excessive heat it should last as long as you need.
I recently moved and setup my reef tank. The tank has begun showing diatoms. Is this product recommend during the tank cycling process? Will it help rid my tank of diatoms?
This product will decrease nitrate levels in the tank by feeding the bacteria and growing the population that additionally consume nitrates. Diatoms will typically not be impacted and usually will fade after a few days without light or siphoning out.
I travel a lot with my job so I can't always dose daily. Can NOPOX be added with a dosing pump?
