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.

NOPOX, as I like to call it, has been an awesome maintenance addition to helping lower Nitrates in my aquariums. I have a tank that had 50ppm nitrates at one point and after 2-3 weeks it was cut nearly in half. Still got a ways to go, but the product works, as long as you religiously dose and follow the instructions to a T. You have to be very careful with this product, as overdosing could mean imminent death to your fish! Red Sea, however, provides very clear and easy instructions, along with an easy to handle measuring cup which helps with getting the right dosage. I'd recommend pouring this into your sump and not directly into your main display tank. Works well if you stick with it! Don't expect overnight results. These things take time!!

After a long battle to reduce organic waste that was feeding algae blooms of all sorts on my reef aquarium I found this amazing product, within days my nitrates came down to 0 ppm! Algae is gone now and my corals are looking simply beautiful. The product should me used in conjunction with Reef Energy A and Reef Energy B to provide nourishment for your corals and a good efficient skimmer. In my case I started with the recommended dose but since then I have come down to 1/4 and still I think it's more than enough. My advice is to start slow, 1/4 for a week and then measure your nitrates , adjust your dose accordingly in small weekly increments, reefs don't react nicely to sudden changes!

Works but I don’t like to use. I should of read up on this online before I purchased. From what I’ve read several articles online/reef forums/blogs on this stuff it can kill all your fish of over dose tank.

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.

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.
