How to use AlgaeBarn Refuge Oxide: Ultra Premium GFO

  General Dosing Guidelines For AlgaeBarn Refuge Oxide: Ultra Premium GFO 
       Start with 1 tablespoon (15g) of GFO per 10 gallons of total water volume.  
     - For example:  
     - 50-gallon tank: 5 tablespoons (75g)  
     - 100-gallon tank: 10 tablespoons (150g)  
     - 170-gallon tank: ~17 tablespoons (255g, roughly 1 cup)  

            Step-by-Step Instructions  

1. Start with a Reduced Dose (50-75% of Recommended Amount):  
   To avoid a sudden drop in phosphate levels, which can stress your tank inhabitants, begin with 50-75% of the full dose. For a 170-gallon tank, this would be 9-13 tablespoons (135-195g).  

2. Place in a Media Bag or Reactor:  
   - Media Bag: Use a fine-mesh bag and position it in an area of high flow, such as your sump or filter chamber.  
   - Reactor: For the best results, use a fluidized reactor to ensure even water flow through the GFO. This maximizes phosphate removal efficiency.  

3. Monitor Phosphate Levels Regularly:  
   - Test your water every 3-5 days after adding the GFO.  
   - Replace the media when you notice phosphate levels beginning to rise again or the media becomes saturated.  

4. Adjust as Needed:  
   - If phosphate levels remain high, you can gradually increase the GFO dose by 10-15% until you reach the desired effect.  
   - Conversely, if levels drop too quickly, reduce the dose slightly to prevent stress on corals and other inhabitants.  


            Key Tips for Optimal Use  
Phosphate Testing: Use a high-accuracy phosphate test kit or meter to track progress. Target levels are typically 0.03-0.05 ppm for reef tanks.  
- Maintenance Schedule: Replace the GFO every 4-6 weeks, depending on your tank's bio load and phosphate levels.  
- Flow Rate in Reactors: Ensure the flow is adjusted so that the GFO gently tumbles, avoiding compaction while maximizing contact time.  


            Directions For a Tank 170 Gallons, that has 0.26 ppm Phosphate
Based on a setup:  
- Start with 12-14 tablespoons (180-210g) of GFO.  
- Test phosphate levels 3-4 days after application to monitor progress.  
- If levels remain high, increase the dose slowly to reach up to 17 tablespoons (255g).  

By using Refuge Oxide and utilizing a reactor for even flow, you should see significant improvements in phosphate management.
