## Description

NO3: PO4-X Contains a unique complex of carbons that are used by nutrient-reducing bacteria. Each carbon is utilized by different strains of microorganisms while maintaining the specific Carbon: Nitrogen: Phosphorus ratio required for each stage. The complex includes other organic bonded elements that are vital stimulators in each stage of the reduction process. These metal and non-metals elements ensure steady bacterial propagation and complete nitrate reduction to nitrogen gas and the absorption and utilization of phosphate by the bacteria. The fine control of the nitrate and phosphate levels provided by monitored dosing of NO3: PO4-X the gradual changes and accurate maintenance of the nutrient levels, preventing destruction of the zooxanthellae population that can cause UV shock and starvation of the corals. Unlike some other low-nutrient regimes, correct use of NO3: PO4-X will maintain all of the beneficial micro fauna. NO3: PO4-X is also recommended as a complete carbon source for use with carbon based de-nitrators. NO3: PO4-X, available in 500ml and 1000ml bottles, also includes a measuring cup for easy dosing. instruction for use: Uncontrolled reduction of the algae nutrients can destroy the symbiotic Zooxanthellae causing UV shock and starvation of the corals. For results always use an accurate test kit such as Red Sea's Nitrate Pro test which has an accuracy of 0. 125ppm. Once lower levels are nutrients are achieved, as seen by corals displaying their natural colors instead of "Zooxanthellae" brown, it is Vital to start feeding with easily digestible foods such as Red Sea's Reef Energy 2-part formula that contains all of the necessary carbohydrates, amino acids and vitamins. Efficient protein skimming is essential to provide the necessary oxygenation of the water and to remove bacterial flocks from the aquarium.

## Questions & Answers

**Q: Can this be diluted with rodi water?**
A: I know of several reef keeper who dilute with rodi water when using smaller doses, although I would contact Red Sea for the right mixture

**Q: I am running vinegar for nitrate reduction. 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
