Description
HTH Green to Blue is a heavy-duty calcium hypochlorite-based pool shock treatment specifically formulated to rescue severely neglected or algae-infested pools by transforming green water back to clean, blue, and swim-ready conditions within 24 hours. Green pool water is caused by rapid algae proliferation, typically triggered by insufficient sanitizer levels, warm weather, or periods of pool neglect. Green to Blue delivers a powerful concentrated dose of shock that kills algae on contact, destroys harmful bacteria, and rapidly restores water clarity in a single treatment. Its fast-acting formula is designed for use as an emergency rescue treatment when standard chlorination has failed to keep algae under control. Packaged in a 2.2kg box, this is an essential product for pool owners facing a green pool emergency who need fast, dramatic, and reliable results without the need for multiple products or complex treatment programmes.
