Better results than bio-pellet reactor

Reviewed in the United States on May 3, 2017

Verified Purchase

I have a 160-gallon mixed reef that has been established for more than 5 years. I have always had un-detectable levels of NO3 and Phosphates (tested with Salifert kits). Last few years, due to some circumstances I neglected my reef and my nitrates shot up-to 100ppm. Needless to say, my corals suffered, primarily due to uncontrollable cyanobacteria. Tried reducing my nutrients with a bigger skimmer, bio-pellet reactor, GFOs and more regular water changes. Even though I switched from frozen foods to just flake food for my fish, my nitrates (possibly phosphates) would not budge that much.

About 20 days ago I started dosing about 15-mls of NoPox. As of today my Nitrates are little under 50ppm and dropping. Once It gets down below 25ppm, I will reduce the dosage to half so that I do not over-shoot the landing. So far I have not seen any negative effects on tank (fish or corals). If anything, my corals are looking healthier and more vibrant. I will post another update in few weeks. But as of right now, I am pleasantly surprised on how well this product as worked out. Currently dosing NoPox manually, but I do plan on adding it to my doser as part of my daily dosing schedule. Btw, first time in many years, my sandbed is sugary white again. I did take my bio-pellet reactor off-line before starting to use this product.

This stuff works, just go slow.

Reviewed in the United States on August 12, 2021

I've used NoPox in my reef for the last 9 months, and I've now started using it in my large FOWLR aquarium as well. There are multiple ways to reduce nitrates in saltwater aquariums, but NoPox (which is basically just methanol and vinegar) makes it very easy.

From my observations, I can tell you a few things. First, start slowly. Nothing good happens quickly in this hobby, and reducing nitrates is part of that. I always begin with a half daily dose for the first week, and scale up from there. That seems to reduce or eliminate the initial bacteria blooms, and if you're keeping sensitive corals it will prevent you from rapidly bottoming out your nitrate and shocking them.

Second, although the product says you shouldn't use phosphate removers in conjunction with NoPox, I've always done so, with no problems. NoPox is highly effective at removing nitrates, but in my experience doesn't really touch phosphates. You can still use phosguard or GFO with this product.

Lastly, make sure you have an efficient protein skimmer running 24/7, and give it 3-4 weeks (or more) before you decide it's not working for you. If you're going slowly, it'll take time to lower your nitrates, but NoPox will do so. Just remember to adjust (as in reduce) your daily dose as your nitrates fall below 5-10 ppm.

Product works as advertised

I've only been using this product for 6 days and have recorded measurable results. I've been battling green hair algae (GHA) in my 90 gallon tank (mostly fish with a few coral) for some time now. My nitrates have always hovered around 10ppm (I never measured phosphates until starting this product). I changed from IO Sea Salt to Seachem Reef Salt, and preformed frequent water changes (15 gallons weekly). In addition, I decreased feedings to the point I was all but starving my fish, and had limited success. After 6-8 weeks of 15 gallon weekly water changes accompanied by manual GHA removal, and starving my fish, my nitrates dropped to about 5ppm, and I did see some GHA starting to turn brown.

When I started this product my nitrates were at 5ppm, and phosphates at .16ppm; so according to the directions I began dosing 8ml per day. After 3 days my nitrates dropped to 2ppm (didn't preform PO4 test), I preformed another 15 gallon water change, and following the instructions, I decreased my dose to 4ml per day. On day 5 my nitrates were 0ppm, and phosphates .08ppm. So now I'm dosing 2ml per day, and will reduce the frequency of my water changes to every two weeks. In addition, I will continue to adjust the NO3PO4x dose until I can maintain nitrates between 1-2ppm as recommended by Red Sea.

During these 6 days, I have seen more of the GHA turning brown and beginning to dislodge from the live rock. I will update this review in a week or two with a report on the GHA battle.

Also, I highly recommend using this product in conjunction with the "Red Sea Algae Control Multi NO3/PO4 Test Kit" to accurately measure your results.

Works but BE CAREFUL!!!!

Reviewed in the United States on April 26, 2014

Well, you could use vinegar and vodka (this is what this product is), but I use to be sure at least I am buying something filtered and to be use in reef systems (so they say).

First time using and I was a bit skeptical, I am being fighting my 10/20 ppm nitrate for a while with mangroves, macro algae and so on, no lucky. So I decided to use this thing. I did miss read the instruction and overdosed my system on the first day (supposed to be 7ml and I added 40ml ), the next day I added 7ml and when I came back from work guess what? the water as white, couldnt see anything at all! Big bacterial bloom right there, I panicked and went to my LFS to buy water (had not enough from my RO) and did a 30 percent water change (water was still cloud about the same). I got better 3 days later and to my surprise my nitrates after 2 years were zero. I did a 30% water change about 4 months ago when I traveled and my nitrates went from 20 to 10 , never 0.

So, I am always adding bacteria here and there, but I think they did not have enough food (carbon) to propagate. I have a lot of live rock and 3 inches sand bad, but something was missing. Now, my system is perfect, although in this event I lost all my mushrooms and a shrimp a had for years, the change was so abrupt they didn't resist the bloom. DONT OVERDOSE!!!! I was a mistake.

I am not giving a 5 stars because the instructions are not clear enough, but I am buying again? for sure!

I am using 7ml every 3 days now just and adjusting as needed , you have to find the balance.

Good luck!
