How To Use Phosban

Do you have Red Slime Algae or Green Hair Algae growing out of control? If you already use Reverse Osmosis water, maybe it is time to consider Phosban or GFO (Granular Ferric Oxide). Phosban helps by removing phosphates and heavy metals from the aquarium water that a variety of algae use to grow. Advanced aquarists also use Phosban to encourage coral growth and enhance coloration. There are two ways of using Phosban.

Phosban In A Media Bag

1. Estimate the amount of Phosban needed, approximately 2 grams per gallon of aquarium water. Over the next few months, you may gradually increase the amount of Phosban to 3-5 grams per gallon. Some hobbyists have reported that rapidly overdosing Phosban can bleach corals due to the immediate increase in water clarity or the rapid decrease is phosphates.

2. Rinse the Phosban to remove fine particles of dust. Do not grind the material together as this will only create more dust! Rinse until the water exiting the media bag is clear. You may also mix Phosban with Carbon to help prevent it from clumping, please note that the carbon will exhaust much faster than the Phosban.

3. Place the Media bag in a high flow area, like a sump or hang on the back filter. From time to time stir the Phosban to keep it from clumping. Phosban will exhaust at different rates. The rate is mostly dependent on how much phosphate is present in the water. As a general rule of thumb, replace Phosban every three months or when phosphate levels are detectable and algae growth increases.

Phosban Reactor

Phosban In A Phosban Reactor

1. Estimate the amount of Phosban needed, approximately 2 grams per gallon of aquarium water. Over the next few months, you may gradually increase the amount of Phosban to 3-5 grams per gallon. Some hobbyists have reported that rapidly overdosing Phosban can bleach corals due to the immediate increase in water clarity or the rapid decrease is phosphates.

2. To rinse the Phosban, place the reactor in the aquarium or sump. Place the return line that would normally run back to the tank into a bucket and turn on the feed pump. When the water exiting the reactor is clear, remove the bucket and discard the waste water. Replace the saltwater with new pre-mixed saltwater.

3. Adjust the flow of the reactor, so the Phosban begins to tumble. This will prevent the Phosban from clumping. Please note, if the Phosban tumbles to vigorously it will grind against itself and create small particles that will be released into the aquarium. Phosban will exhaust at different rates, mostly depending on how much phosphate is present in the water. In general, replace Phosban every three months or when phosphate levels rise and algae growth begins to hasten.

Phosban is an effective method of removing Phosphate (PO4) from the water. This can help combat Green Hair Algae and Red Slime Algae, as well as promote healthy coral growth and enhanced coloration. Remember to use a small dose when starting a Phosban regimen and then gradually build up to avoid coral bleaching. It is also important to Test Phosphate levels to help determine when the Phosban has been exhausted.
