1 qt 90-Day Algaecide Bottle (TECH ONLY)
Product Overview
A long-lasting preventative that pool techs use to maintain water clarity for up to three months with a single dose.
This 1 QUART bottle of Regal 90-Day Algaecide features an 11.8% Copper triethanolamine complex* formula designed for extended protection. In our experience, this chelated copper treatment is a proven choice for preventing algae blooms without the need for weekly additions, making it the standard specification for low-maintenance pool care. It reliably handles the prevention of green, black, and mustard algae in all pool types.
Benefits & What Makes It Different
11.8% Copper triethanolamine complex*
This chelated formula stays in suspension longer than standard copper sulfate, providing consistent protection against green and mustard algae.
90-Day Residual Protection
One application of this 1 QUART bottle reliably handles algae prevention for a full three months, reducing the chemical workload for homeowners.
Non-Staining Formulation
The chelation process keeps the copper active in the water rather than precipitating out, which helps prevent the staining of pool surfaces when used as directed.

Pro Tip
Always test your pool's metal levels before adding copper-based algaecides; if your source water already has high copper content, use a sequestering agent to prevent potential scaling or discoloration.
Common Questions & Instructions
How often should I apply the Regal 90-Day Algaecide to my swimming pool?
For continuous protection, apply one dose every 90 days; however, heavy rainfall or frequent backwashing may require more frequent testing of copper levels to maintain efficacy.
Will this 11.8% copper algaecide cause my pool water to turn blue or stain the plaster?
Because this product uses a Copper triethanolamine complex*, the copper is chelated to stay in solution, significantly reducing the risk of staining compared to non-chelated copper products.
Can I swim immediately after adding the 90-Day Algaecide to my pool?
We recommend waiting at least 15 minutes for the product to disperse through the filtration system before swimming to ensure the chemical is properly diluted.
