Abstract
Disclosed are trichloroisocyanuric acid compositions that have improved algicidal and/or fungicidal properties yet are relatively safe and non-corrosive. The compositions preferably contain between about 50% and about 95% TCCA, between about 0.5% and about 7% glycoluril, between about 2% and about 40% alum, and between about 2% and about 40% borax. The compositions generate substantially less chlorine gas than would be expected from the teachings of the prior art, especially when wet. The inventive compositions are therefore less toxic and less corrosive.
