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.

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.

Exceptional Product - Zero Phosphates!
It has been three weeks since our last water change on our small 40 gallon tank. Typically a reef tank, especially smaller tanks and nanos, will require a 10% change weekly, usually due to phosphates. After a gauntlet of tests this past weekend, everything came up zeros or near zeros, specifically phosphates were zero, necessitating only a light cleaning of our protein skimmer and topping off the water and salt content. This shows how effective this product is. We have been using another brand of crystals in a medium bag and not only was there consistently a small amount of phosphate, but measuring the medium, buying media bags, etc. make phos- zorb a clearly superior product. We will never go back. This prepackaged phosphate medium went straight into the fourth stage of a UV canister filter (after a quick rinse) three weeks ago and hasn't been touched since. Our 40 gallon reef tank thanks phos-zorb for keeping the fish, anemones, shrimp and most importantly the SPS and LPS corals healthy.
