Specification
Benefits of Trichloroisocyanuric Acid in Swimming Pool
1.It's available with 90% chlorine concentration.
2.It's due to high chlorine content,easy handling for large pools.
3.It may reduce chlorine loss during day time.it is stable and does not strip like any other halogen compounds.
4.It will reduce algae growth.
5.It dissolves slowly in water, so that it allows for continuously metered dosing of available chlorine, especially when in tablet form.
