Reasonable product no instructions how to use.

HD Chemicals are from previous experience a fine firm, with helpful operatives. However in the case of sulphamic acid the powder turned ip in good time but no clue given as to recommended usage or dilution percentage. As an acid this should be compulsory rather than let consumers make their own minds up. This is simply laziness surely?
