Phosphate Control

Phosphate Control

Phosphate is essential to the survival of a reef aquarium. Too much will result in too many algae. Too little and your fish and coral will starve. You must be able to maintain just the right amount to have a beautiful reef and a pristine tank. There are three treatments to use that will do just that. The first treatment is GFO or Granular Ferric Oxide. GFO is placed into a media reactor where it slowly absorbs phosphate. GFO also helps to prevent clumping. On advantage of using GFO, it absorbs phosphate slowly and will not shock the system. The disadvantages of using GFO are it will drop the water alkalinity and calcium. So, it is best to test your water regularly. Another treatment is Aluminum Oxide. This treatment is fast acting and very quick to remove phosphate. Using Aluminum Oxide can be tricky, and if you use too much at the same time, it can shock the corals if the phosphate level drops too quickly. The last treatment to lower phosphate is liquid phosphate removers. This liquid is deposited directly into the water. Of the three, liquid phosphate is the most commonly used treatment since it is more economical to the other two options.

There are other ways you can help to lower the phosphate levels in your aquarium. The first is try not to overfeed. Overfeeding is one of the leading causes of increasing phosphate. Ensure the protein skimmer is the right size for your tank, continually working, and kept clean to remove organic waste. Having a Refugium also helps to lower phosphate. Another is over shocking your aquarium. Over shocking may result in total phosphate removal. When this occurs, the coral and fish will starve which can lead to death. So test your water before you shock. You may not need to shock if the phosphate level is at the right level.
