This product is the best P04 remover I have tried. I had very high levels of phosphate build up in my aquarium water around 10 (mg/L) which caused hair algae and poor plant growth, totally spoiling the look of my aquaruim. After adding JBL phosphateEx Ultra to my canister filter the results are amazing within a week the P04 levels went down to just 0.5 (mg/L) and have remained that way for over 3 weeks (so far so good!) With a manufactors claimed shelf life of 6 months before replacement it's excellent value. I would definetly recommend this 5 Star product and will purchase it again.
