Its unique carbon complex stimulates beneficial bacteria to safely reduce nuisance algae while enhancing coral growth and coloration. Designed for reef-safe, gradual nutrient management, it maintains essential micro-fauna and supports optimal zooxanthellae balance for vibrant, healthy reefs. ## Description NO3:PO4-X ALGAE MANAGEMENT A complete, reef-safe, controllable solution for nitrate & phosphate reduction NO3:PO4-X is the original, safest, most popular, and best solution that provides a full, reef-safe, controllable method for nitrate and phosphate reduction, thereby boosting coral growth and coloration in any reef or marine fish system. Unlike other methods, the monitored dosing of NO3:PO4-X biologically reduces both nitrate and phosphate, while enabling the fine control of their levels. This fine control allows gradual changes and guarantees accurate maintenance of algae nutrient levels required to safely reduce nuisance algae and bring the symbiotic zooxanthellae algae to the optimal levels needed for boosting coral growth and coloration. NO3:PO4-X is a unique complex of carbon substances and other organically bound elements that enhances the activity of nutrient reducing bacteria, which naturally exist in all marine aquariums. Each carbon source in the complex is utilized by different strains of microorganisms and together with the balanced ratio of enzymatic co-factors guarantee a complete and safe denitrification process (nitrate reduction) and phosphate reduction in the aquarium.

How long do I need to stop the vinegar before I start this??** A: Suggest you call Red Sea. Their customer service with this product is helpful. Alternatively, you can also send an email. I've used both methods in successfully communicating with them. **Q: Does this take longer for large tanks? I have 150 gallon s with a 68 gallon sump.** A: tank size does not matter I have 180, and I dose it with a dosser which is the best way to reduce nitrates, this stuff is excellent....it will take a while for the bacteria to form (should not be more than a month) , you will notice first a white film on your glass, once that starts the bacteria is growing and the white will disappear, the fish and snails love the bacteria. Again it needs to be done daily and your nitrates can be either gone, or reduced down to nothing if you prefer to have just a small amount. Again a dosser is the best method Jaebo cheap and works well under 60.00 Hope this helps **Q: Can this be used in a freshwater aquarium?** A: It is suggested to use for salt water aquarium ## Customer Reviews ### ⭐ Not working *by on Reviewed in the United Arab Emirates 20 March 2024* Not working don't waste your money ### ⭐⭐⭐⭐⭐ Perfect *by on Reviewed in the United Kingdom 21 May 2024* Buy this all the time for my marine tank ### ⭐⭐⭐⭐⭐ 確実な効果ですが　高い *by on Reviewed in Japan 29 December 2024* 効果あるけど、どんどん値上がりしている＊０００円越えはありえない！！！　他の代用品を検討したい製品名 100日あたりのコスト 円Red Sea - NO3:PO4-X 3000べっぴん珊瑚 - すっぴん 667Tropic Marin - NP-Bacto-Balance 1380Fauna Marin - Ultra Bio 2400Continuum Aquatics - BacterGen MD 2200 ## Frequently Bought Together - Red Sea NO3:PO4-X, Nitrate and Phosphate Reducer, 1 Liter - Red Sea Aqcult 306168 1 LTR Reefer Foundation B Alkalin - Aqcult 306167 1 Ltr Red Reefer Foundation A Calcium & Strontium --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/279416994-red-sea-no3-po4-x-nitrate-and-phosphate-reducer-1l](https://www.desertcart.gr/products/279416994-red-sea-no3-po4-x-nitrate-and-phosphate-reducer-1l) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-22*
