Used this in my 15-gallon freshwater tank. The water became noticeably softer after a week. My fish seem more active and the water clarity improved. Easy to replace and no fish stress reported.

Works well for reducing water hardness. The pouch fits nicely in my filter. I noticed a reduction in calcium deposits on the tank glass after a few weeks. Slight improvement in water flow, but not dramatic.

Great product for maintaining soft water. No fish health issues. The media is easy to install and lasts longer than expected in a 20-gallon tank. Clean and effective.
