API Phos-Zorb 5.25oz Information

Phos-Zorb is a special filtration material that selectively removes phosphate and silicate, common nutrients found in fresh and saltwater aquariums. In saltwater aquariums, excess phosphate lowers the available calcium and magnesium necessary for the growth of hard corals and other invertebrates.
  • Removes phosphate and silicate
  • Removes phosphate, a by-product of fish metabolism and decaying organic matter and an additive in some tap water supplies, aquarium products and filtration media
  • Will not remove trace elements
  • Will not affect pH
  • Treats up to 55 Gallons

Comments: I have used most of the Phosphate removal products on the market and they all seem to work the same. However, when I came across Phos-Zorb, I had to try it. All I can say is WOW! My algae growth is down and my tank looks great! My corals and fish are happy and that makes me VERY happy! It's all I use now!

Comments: After my heater had a poltergeist and cooked most of my coral, I developed a cyanobacterium overgrowth. Water changes just weren't enought to stabilize the water chems. Between the Phos-Zorb and the Nitrate reducing pads, the cyanobacterial growth is almost nill! Whew! Good product

Comments: This works great. I have used it for years. I used it on my Ciclid tanks for years. I have a 90 gal Salt water tani and I add one pack per 2 months than check, if phosphates are rising, I replace it. 2 to 3 monthes live span. Best phosphate remover.

Comments: Had bought a Rena Filstar XP3 to use in my 75 gallon tank with 20 gallon sump.I had a problem with Brown Hair Algae from using just filtered tap water with an additive. Installed 2 of the Phos-Zorb in the Filstar and within 2 days noticed the algae withering.In a week it was gone! Will continue to use this product and highly recommend.
