Periodic Products CuLator Ultra 4.0 is formulated to capture and hold dissolved metals without phosphate-based sequestrants or harsh additives. Designed for simple, hands-off use, the product treats large volumes and gives a visible color change as it removes metals so you can see it working.\u003c\/p\u003e\n\n\u003ch3\u003eHow does CuLator Ultra 4.0 remove metals from my pool?\u003c\/h3\u003e\n\u003cp\u003eCuLator Ultra uses a proprietary absorbing medium inside a durable, mesh pouch that sits in the skimmer or pump basket.
