General instructions for testing NO3 & PO4 and dosing NO3:PO4-X:

1. Only use NO3:PO4-X according to the enclosed instructions.
2. Test only with high resolution test kits such as Red Sea’s Nitrate & Phosphate colorimetric comparator Pro Kits.
3. The NO3:PO4-X dosing chart (on back of product) is based on treating 100 liters / 25 gallons of water. Estimate your total volume of water (aquarium & sump less volume of live rocks etc) to calculate the correct dosage for your system.
4. NO3:PO4-X should be added to the sump. If you do not have a sump, add NO3:PO4-X slowly to an area with high water flow to prevent direct contact with the corals.
5. Efficient protein skimming is essential to provide the necessary oxygenation of the aquarium and to remove bacterial flocks from the water.
6. NO3:PO4-X must be added consistently on a daily basis to prevent starvation and destruction of the nitrate and phosphate reducing bacteria. If you miss one or more days of using NO3:PO4-X do not add the amount that you have missed and resume the dosing at the current daily dose.
7. For optimal results It is recommended to add NO3:PO4-X with a dosing pump.
