Know before you buy
This agent works by binding to suspended particles in your water, causing them to clump together and become heavy enough to sink to the pool floor. Once the debris has settled, you can easily remove it by vacuuming it directly to waste.
The recommended dosage is one pound of granular treatment for every 5,000 gallons of water. Since this container holds two pounds, it is sufficient to treat a total of 10,000 gallons.
Yes, this product is formulated to be safe and effective for both swimming pools and spas. Ensure you follow the dosage instructions carefully based on your specific water volume.
No, you should turn off your filter system after applying the product to allow the water to remain still. This stillness is necessary for the particles to settle effectively to the bottom of the pool.
Nu-Clo Flock is composed of 100% Aluminum sulfate. This is a standard, highly effective chemical compound used specifically for flocculation in pool and spa maintenance.
