Which of the following are brand names or types of copper TEA products?

• A. Roundup, Rodeo, Reward.
• B. Cutrine, Captain Clearigate, K-TEA
• C. SeClear, CuSure, AlgaAway
• D. CopperSafe, AlgaEx, TeAqua.

Answer: (B)

Copper TEA products are copper-based algaecides formulated as copper triethanolamine complexes, designed to control algae in aquatic systems. The best-supported brand names for this type of product are Cutrine, Captain Clearigate, and K-TEA. Cutrine is a long-known copper TEA product used to treat algae in ponds and lakes; Clearigate (often seen as Captain Clearigate) is another copper TEA formulation marketed for algae control; and K-TEA is specifically the TEA-based copper product named to highlight that copper TEA chemistry. The other options mix in herbicides or different copper formulations that aren’t copper TEA products, so they don’t fit the category as described.
