First off, my apologies if this post is in the wrong place. In the last 3 weeks my water has become hazy. It is not Green but I can see tiny particles that are not being trapped by the fine filter media (I use pond filter wool from Ebay that I cut to size) Nothing has changed in the tank during this time.Water changes are done 30% each week. I dose PO4 and KN03 along with Profito and pressurised c02. Water parameters are 0 ammonia 0 nitrite. My question is, would Purigen help with this or would Seachem Clarity be a better option. My thinking was maybe Purigen, as I could leave this in the filter and replace with another pouch when I clean the filter. If I go for Purigen, where, in my Eheim 2060 should it be placed?
