Bromo-chlor-odimethyl-hydantoin
> Incompatible with chlorine donors in tablet form
> It should not be stored with or mixed with any other pool chemical
> Personal protective clothing must be worn when handling BCDMH
> Storage should be in a cool, dry, well ventilated secure place


FEATURES
> White tablets
> Contains both chlorine and bromine
> Popular for use in spas
> Not suitable for semi commercial or commercial pools
> High hydantoin levels have been blamed for skin irritation although this has never been proved
> Hydantoin is difficult to test for but must be controlled by dilution
> Fairly neutral pH
> Needs regular shock dosing to regenerate the bromamines


DOSING
Dosing is via a brominator, which is an erosion feeder fitted across the circulating system, post circulating pump to post heater. Feeder must be clearly marked to prevent accidental filling with trichlor or cal hypo tablets. An explosion could result.
