PhosNet

Initial Setup

1. Determine the Required Amount:

   • Use 50 grams (1/2 cup) of Seachem PhosNet for every 200 liters (50 US gallons) of saltwater or 400 liters (100 US gallons) of freshwater.

2. Rinse the Media:

   • Rinse PhosNet thoroughly with freshwater to remove any dust or debris before placing it in the filter.

3. Place in Filter:

   • Filter Bag: Place the rinsed PhosNet in a filter bag.
   • Canister Filter: Place the filter bag in the media basket of the canister filter.
   • Other Filters: PhosNet can also be used in chemical filtration modules, box filters, or any high-flow area of a trickle filter.

4. Start the Filter:

   • Turn on the filter and ensure proper water flow through the PhosNet media.

Maintenance

1. Regular Monitoring:

   • Test phosphate or silicate concentrations with a reliable test kit (e.g., Salifert Phosphate or MultiTest Silicate) after 4 days of use.
   • If the concentration has not dropped to around 0.02 mg/L, replace the PhosNet. Otherwise, leave it in place until levels begin to climb again.

2. Replacing the Media:

   • Replace PhosNet every 4 to 6 weeks, or when you notice a decline in water quality.
   • Rinse the new media thoroughly before placing it in the filter.

3. Rinsing the Media:

   • During routine maintenance, rinse the PhosNet with aquarium water to remove any accumulated debris.
   • Avoid using tap water, as chlorine and chloramines can harm beneficial bacteria.

4. Storage:

   • Store Seachem PhosNet in a cool, dry place.
   • Ensure the container is tightly sealed to prevent moisture absorption.

1. How often should I replace PhosNet?
   Replace PhosNet when phosphate or silicate levels begin to rise again, typically every few weeks depending on your aquarium’s conditions.

2. Can I use PhosNet in a reef tank?
   Yes, PhosNet is safe for use in both freshwater and saltwater aquariums, including reef tanks.

3. Will PhosNet affect my aquarium’s pH?
   No, PhosNet has minimal impact on pH levels due to its low ash content.

4. Available Sizes?
   500g
