“I have used the much more pricey brands of GFO in the past and found this to be a much better value and does the same job if not better!! I have a 90 gl and 135 gl and I used alot of GFO and will be coming back for more very soon!”

“I have used Kolar Filtration GFO for the past year and my hair algae and phosphates have dramatically decreased leaving me with a beautiful colored rock and coral setting. A+ and I would recommend them 100% for quality and price of their product.”

“Absolutely love Kolar Filtrations’ GFO phosphate removal media, as I’ve been using it now for about just over a year. Keeps the algae at bay, letting my tank look its best. This is by far the best GFO phosphate removal media I’ve ever used.  Would definitely recommend this to others! 5 complete stars!!!”
