*	Chemical filter media scientifically proven to reduce phosphate and silicate
*	Effectively removes phosphate to help reduce aquarium maintenance caused by excess phosphate
*	Provides long-lasting phosphate control in fresh or saltwater aquariums

A specialized, synthetic adsorption filtration media that selectively removes phosphate in fresh and saltwater aquariums, as well as silicate found in tap water. Phos-Zorb effectively removes phosphate and silicate and will not release them back into the water for long-lasting phosphate control. A clean aquarium environment free of excess phosphate means enhanced growth of corals in saltwater aquariums and superior plant growth in freshwater aquariums.

Phos-Zorb also helps prevent calcium precipitation caused by excess phosphate in reef aquariums to help promote the growth of reef-building corals. Effective for up to 8 weeks. Safe for all fish, invertebrates, and plants. Net weight 5.25 oz in mesh bag. Treats up to 55 gallons.

API Phos-Zorb 5.25 mesh bag 4.3 5 8 8

Works as advertised The short and simple story here is that API's Phos-Zorb does what it says it will do: remove phosphates, as well as silicates. I have an established 36-gallon planted goldfish tank that's been plagued by diatoms for months. The diatoms/brown algae love to anchor themselves on leaf surfaces of most of my broad-leafed plants, i.e. anubias, echinodorus bleheri (Amazon swords), etc., thanks in part to the high-ish mineral content of the hard water in my neighborhood. Phos-Zorb is an easy to use, plug-n-play product; after rinsing off a new pack I simply placed Phos-Zorb at the top of my filter where it's in the highest flow area. While my phosphate levels weren't ever high enough to be of great concern I nevertheless wanted to reduce them as much as possible to help combat the diatom issue (as best I understand how phosphates are involved in the process of creating an environment favorable for diatoms). Two weeks now after first installing Phos-Zorb and my phosphate levels are as close to 0 ppm as I can tell by using API's phosphate-specific test kit. Additionally, silicate levels remain between 0 and 1.5 ppm according to Seachem's silicate-specific test kit, a significant reduction from the 6.0-plus ppm levels beforehand. The salient point is that while the existing presence of diatoms hasn't entirely dissipated, Phos-Zorb appears to have severely stunted new growth of the brown algae/diatoms. Since first using the product, new growth leaves on my plants currently remain free of brown algae, whereas before using Phos-Zorb new growth leaves would've shown signs of flourishing brown algae within a two-week period. *As a side note, using a higher quality food and reduced feeding amounts likely has also helped reduce phosphate levels in my tank.

good product Love it. This was a replacement and it worked great. February 17, 2014

Great Product It drastically cuts down on my algae and when I finally start seeing algae, it's lighter in color and much easier to scrape off of the glass and ornaments. September 3, 2013

Great Product with excellent results. I have been using API phos zorb for close to 5 years now with better than excellent results. I was having this brown growth starting to form all over everything in my tank which was well established and couldn't figure out why. I learned these where diatoms caused by either high phosphate or high nitrate. I did 70% water change every week to keep the nitrates at low levels so it had to be the phosphate. I bought from DR Foster& Smith the complete API fresh water test kit and found there was no Nitrate in my water supply but a considerably high phosphate level. So I tried the API Phos Zorb and literally in days my problem was solved. This product is a God send and works extreimly well. It must be changed every 2 months which is a great time to service the filter as well. Highly recommended if your serious about your water quality. April 23, 2012
