Red Sea NO3:PO4-X 500ml NOPOX - Nitrate & Phosphate Reducer for Reef Aquariums, Promotes Healthy Coral Growth, Controls Algae & Maintains Water

I recently suffered a massive system crash due to high phosphates leaching into my topoff water from the reservoir. I decided to add Red Sea NO3:PO4-X Nitrate & Phosphate Reducer to my repair plan and just see how it went. Now, bear in mind that this was just ONE PART of a multi-step battle plan, so I can't say for sure what worked better, or if anything was useless, or if this was all just blind luck by a dumb guy with a tank, but who knows. I do think it helped, so here's my review: Naturally, Amazon shipping was quick. I read the rest of the reviews, some good, some bad, and decided to give it a go. First off, be sure to read the entire instruction packet. It might seem silly, but there are different dosing regimens for different things you want to do to your tank, so read 'em. When I opened the bottle, I was assaulted by the heady aroma of vinegar and....SOMETHING. Something alcoholic, I think. Yep, you guessed correctly....this stuff is basically a "proprietary blend" of carbon sources. In other words, this is carbon-dosing for idjits. I have no problem with this. I have been afraid of carbon dosing because it seems too fiddly. This product dumbs it down for the rest of us and makes it a relatively easy task. The only thing you need to know about carbon dosing, though, is that once you start, you need to make sure it's done daily. If you decide to stop you need to wean the tank off of it. It's going to promote extra bacterial growth, which will in turn metabolize phosphates and nitrates and bring those terrifying numbers back into an acceptable range. The product claims that this will also promote clarity of the water and greater polyp extension. Well, it's been a few weeks since I started, and I can definitely see a lot of improvement. Dunno if it's the GFO, the UV filter, the massive water change, the Red Sea Reducer, or (most likely) a combination off all of the above. But I DO see much clearer water and coral polyp extension has been great, so I'm gonna go ahead and call that a win for this particular product. My phosphates have dropped from 0.18 on a Hanna checker down to 0.02, and my tank is back to happy again. I'd recommend this product, but I want people to be aware that this IS a carbon dosing source, and those instructions have to be fully read and understood before you start.

It took a while to arrive and based on what I read online I started slowly using about 1/2 the recommended dosage. It worked a little, so I increased the dosage to recommended levels. Wow! It works great and has reduced the nitrate level in my fish only tank considerably and my algae problem is under control. Note, I dosed by hand daily as I do not have a dosing pump.

Heard nothing but good stuff about this. I had problems with high nitrates in my predator fowlr tank. I didn't want to do macro of biopellets. Besides I heard this stuff work much better and faster. I got 100 g DT and 55 sump. I called red sea and they gave me the info I needed for how much to dose my tank, depending on your nutrients levels. I'm dosing the max dose 3ml per 25 gallons. Its been a week since I've started dosing and my nitrates were at 80ppm before dosing. Now there at 20a week after dosing. I have a yellow head moray eel and Him alone is a big bio load. I'm already satisfied with results and it haven't been a month of using this product. I don't need undetectable nitrates But under 20 I can live with. I'll be using this as long as im in the marine hobby.

Fantastic product. Had terrible problems with nitrates. Tried less feedings and more water changes but neither worked. Nitrates dropped to zero in less than a week in my Biocube 32 with this product. I found the directions to be pretty straight forward. YOU MUST RUN A SKIMMER WITH THIS PRODUCT. An air stone might work if you absolutely can't run a skimmer. The water needs to be kept airated while using this product. Also, try not to add the product to the water where fish or corals are present if you can. Add it to your sump or in my case I added it to chamber three of my Biocube. All of this is in the directions. Again fantastic product.

I’ve always used this product. This time it took a little longer to arrive though.

I'm giving this product five stars as it definitely has some kick to it. Now, when it comes to my Nitrates, I saw them drop from 40ppm to 20ppm after my tiny dose of this stuff. My tank is small and houses jellyfish. I added literally just the smallest dosage I could, it was like a few drops, and the next day my tank was hazy/cloudy. Had a bacteria bloom that fortunately did not hurt the jellies at all. If I had coral or plants they may have been in trouble. The bloom put a film on the bottom and it looked like a flowing "fog" moving with the currents of the tank. By the next day the fog was gone -- and the tank had dropped in Nitrate. My big concern was maybe the bacteria overtook my Ammonia consuming bacteria, but my ammonia levels are still great and the jellyfish seem as happy as can be; more active than before. It also put a dent in the growth of some red algae. I had to rub off the film and pull out some water with the film in it, but that was about it. I wish my Nitrates dropped to zero, but I'm just glad they came down. Be sure to have your oxygen pumping when dosing, as it seems to use up a lot of the oxygen in your water, causing PH to drop. By pumping oxygen at a higher rate you can counteract the effect and help it do its thing.

Within two weeks, algae is receding, and nitrates have dropped from 20ppm to below 5ppm. Can cause a bacteria bloom, causing cloudy water but clears in less than day. In all honesty, I probably miscalculated the amount of mls needed by a ml or so due to water volume calculation; I tried to factor in rocks, and sand. By best advise is to round down using slightly less, and ramp up, if needed, after a week.

I've been using this product for three weeks and my nitrate level is down to 0.25 ppm. The nuisance algae has disappeared. I have several LPS coral in the aquarium so I will want to maintain this level of NO3. I am not concerned with the phosphate level at this point. The product had no visible ill effects on any live stock. This product can be toxic so care should be taken as to the dosage and location of introduction to your aquarium (add to sump if possible). Follow the directions and understand the process and you should be happy with the results.

livraison trop longue presque 3 semaines pas encore reçu, terminé je l achète chez concurrent. Sinon produit au top pas de po4 et no3 , 1ml tout les jours de l année , le meilleur produit que j ai utilisé, essayé d autres marques moins efficace ,super pour mon aquarium récifal de 125 litres.

It works. The only one chemical I use in my 90 gal marine set up. Could not live without it

Keeps my tank nitrate under control.

Excellent product, shipped well packed and arrived as advertised.
