Good value for money

A little goes a long way. One box lasted me the entire summer season for my medium-sized backyard pool. Will buy again next year.

Effective but follow instructions

Works very well against stubborn algae. Make sure to brush the walls while using it for best results. Slight blue tint initially but clears up.

Easy to use tablets

Much easier than measuring out liquids. I just drop them in the skimmer basket and let them do the work. No more green slime!

Great for large landscape pools

We use this for our community park pool. It handles the heavy load effectively and keeps maintenance costs down compared to liquid algaecides.

Saved my green pool!

My pool turned completely green after a week of neglect. These tablets worked wonders within 48 hours. The water is crystal clear again.

5 FAQ

Q: Does this kill black algae as well?

A: While primarily designed for green algae, it can help suppress black algae when combined with vigorous brushing and standard chlorine shock treatments.

Q: How many tablets do I need for a 20,000 gallon pool?

A: For initial treatment of visible algae, use 1 tablet per 5,000 gallons. For maintenance, reduce to 1 tablet per 10,000 gallons weekly.

Q: Can I swim immediately after adding these tablets?

A: It is recommended to wait at least 4 to 6 hours after dissolution and circulation before swimming to ensure chemical levels are balanced.

Q: Is this safe for saltwater pools?

A: Yes, this copper sulfate algaecide is compatible with saltwater chlorination systems when used as directed.

Q: Will this product stain my pool liner?

A: When used according to the dosage instructions, copper sulfate tablets should not stain liners. Avoid placing undissolved tablets directly on the pool floor.
