I started using this PO4 x-port product a few days ago to see if it will maintain or better, reduce my levels. My GFO was exhausted so I emptied the reactor and filled with x-port cubes. I followed the instructions though the part about adding to a bucket of tank water was really vague... just like so many other products out there. So after rinsing, and rinsing, and rinsing, and rinsing some more, I added to my reactor. WOW this stuff too a lot of rinsing. Then I ran more tank water through the reactor slowly until it ran clear, approximately 3 gallons of tank water.

My PO4 had climbed to 0.12 at the time the GFO became exhausted and 3 days after starting this new product that number is holding steady. It is too soon to tell but at least PO4 levels are not climbing as it would if I were not using anything at all. I'm going very slow and only starting with approx 1 cup of media in my reactor. I will let it run a week and then slowly increase the amount of media. I'm still skeptical and ready to start up GFO again at any time just in case.
