Poly-Bio-Marine Poly-Filter is a chemical filtration pad that absorbs heavy metals, phosphate, organics, and other contaminants. It changes color as it absorbs.
Why We Use It
The color change tells you what's in your water. It's a great safety net and diagnostic tool.
Use: Place where water flows through it, and replace when it's discolored.
