Works well but pricey

The product does exactly what it says regarding clarification, but I find it a bit more expensive than other brands I have tried. Good quality though.

Great for algae prevention

I use this weekly in my backyard pool during the summer. It keeps the green algae away without needing heavy chlorine shocks. The only reason for 4 stars is the bottle cap could be easier to open.

Saved my pool opening

Opened my pool early this year and the water was a mess. This product acted as a great activator to get the filtration system working efficiently again. Very satisfied.

Perfect for my sauna steam generator

I was worried about using chemicals in my sauna, but this enzyme-based formula is gentle and effective. It prevents buildup in the steam generator nicely.

Crystal clear water in hours!

My hot tub water was cloudy after a weekend party. I added the recommended dose of Yongweishi, and within 4 hours, the water was sparkling clean. Highly recommend for quick fixes.

No more cloudy spa water

As someone with sensitive skin, I appreciate that this doesn't irritate my eyes or skin like traditional algaecides. Keeps the spa water pristine.

5 FAQ

Q: How long should I wait before swimming after application?

A: For best results, we recommend waiting at least 30 minutes after circulation has distributed the product evenly throughout the water.

Q: What is the dosage for a 500-gallon hot spring?

A: For a 500-gallon capacity, please add approximately 2 ounces (60ml) of the solution. Always refer to the label instructions for specific conditions.

Q: Does this replace chlorine completely?

A: No, this product is a clarifier and algaecide supplement. It works best alongside your standard sanitation routine (chlorine or bromine) to maintain balanced water chemistry.

Q: Can this be used in saltwater pools?

A: Yes, Yongweishi Enzyme Clarifier is safe and effective for use in both freshwater and saltwater pool systems.

Q: Is this product safe for pets if they drink the pool water?

A: While our enzyme formula is non-toxic, we generally discourage pets from drinking pool water treated with any chemicals. Please ensure fresh drinking water is available for them nearby.
