AQUAPERL Plus is a specially formulated perlite developed explicitly for the aquatics industry Perlite is an important filtration medium used for swimming pools and other water filtration applications a unique property of perlite is that it expands up to 20 times its original volume when heated to its softening range this expansion is caused by water in the crude rock when perlite ore is rapidly heated above 850°c the water vaporises causing the softened rock to expand tiny glass like bubbles are produced which account for the lightweight and exceptional physical properties of expanded perlite Perlite is a generic name for a naturally occurring siliceous volcanic rockPerlite filter aids do not impart taste colour or odour to liquids being filtered and they are virtually insoluble in mineral and organic acids at all temperatures comparative products such as diatomaceous earth DE sand and zeolite are also used in filtration DE can contain high levels of crystalline silica DE sand and zeolite are much heavier than perlite and for products sold by the kilogram this often makes them more expensive than perlite perlite is at least 30 per cent lighter than these competing materials Aquaperl is avaiable in 4.5kg bags pick up only at springfield nsw Call for pick up infomation 0431 047 179
