Spa & Hot Tub Chemistry 101 with Solenis

Treat spas differently than pools: Hot water, high bather loads, and constant aeration drastically alter chemical behavior, requiring a tailored approach to avoid problems.

Prioritize water balance before sanitization: Always adjust alkalinity, pH, and calcium hardness first, and then introduce sanitizers to ensure optimal effectiveness and prevent equipment damage.

Utilize bromine for hot water efficacy: Bromine often performs better than chlorine in hot water due to its stability at higher pH levels and temperatures, making it a reliable choice for spas.

Shock and oxidize regularly: Implement a weekly shocking program and educate clients on shocking after each heavy use to remove bather waste and regenerate sanitizers, especially with bromine.

Address biofilm proactively: Biofilm is a major issue in spa plumbing; regular purging with dedicated products (every 90-120 days) and consistent chemical cleaning of filters are crucial for sanitation and longevity.

Educate clients on spa maintenance: Clearly communicate the importance of post-use shocking, temporary cover removal for aeration, and the need for regular draining/refilling to manage expectations and ensure proper spa care.

Consider supplemental products: Enzymes, clarifiers, and sequestrants, when used proactively, act as an 'insurance policy' to improve water quality, reduce chemical consumption, and prevent issues like foaming and staining.
