Calculators
Calculators. With these calculators you can calculate AngloAmerican units to the standards units (SIunits). This may be useful, because most American and British use American or British units and European use the standard metric units. With the conversion calculators you can convert the units that are most commonly used.
Water treatment chemicals
Algaecides Algaecides are chemicals that kill algae and blue or green algae, when they are added to water. Examples are copper sulphate, iron salts, rosin amine salts and benzalkonium chloride. Algaecides are effective against algae, but are not very usable for algal blooms for environmental reasons.
