I put a Purigen 100ml pouch into my filter 18 hours ago. The water was a rich dark brownish red tea color, Today the water is almost clear and my filtration system is actually kind of small (supplemental with a air powered sponge filter). I am realy amazed at how well this works and would recommend it for anyone trying to clear up their water.

Also my water parameters have not moved and my shrimp are just as happy as ever.
