Sizing depends on three factors: <\/p>\n<ul>\n<li><strong>The volume of your pond<\/strong>: as a rule of thumb, the entire volume should be filtered in 4 to 6 hours maximum.<\/li>\n<li><strong>Your pump&#8217;s flow rate<\/strong>: the filter must be able to handle the flow rate without excessive pressure drop.<\/li>\n<li><strong>Ancillary equipment<\/strong>: counter-current swimming, solar heating, hydraulic robots&#8230; all increase requirements.<\/li>\n<\/ul>\n<p>Our technicians will visit you free of charge in <strong>Geneva<\/strong> (Versoix, Cologny, Carouge), La C\u00f4te<strong>(Nyon<\/strong>, Gland, Rolle) and throughout the canton of <strong>Vaud<\/strong> (Morges, <strong>Lausanne<\/strong>, Pully, Vevey, Montreux) to analyze your installation and recommend the right model.[\/vc_column_text][vc_empty_space height=&#8221;15px&#8221;][\/vc_column][\/vc_row][vc_row equal_height=&#8221;yes&#8221; css=&#8221;.vc_custom_1765347898497{background-color: #FFFFFF !important;}&#8221;][vc_column width=&#8221;2\/3&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>The secret of crystal-clear water: filter media<\/h2>\n<p>[\/vc_column_text][vc_empty_space height=&#8221;5px&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h3>Filter Media: AFM glass or traditional sand?<\/h3>\n<p>The filter is the body, but the media inside is the engine. We always recommend AFM activated glass (Dryden Aqua) rather than traditional sand. <\/p>\n<h4>Why AFM glass is superior to sand<\/h4>\n<ul>\n<li><strong>Fine filtration<\/strong>: retains particles down to 1 micron (compared with 40 microns for sand)<\/li>\n<li><strong>Anti-bacterial<\/strong>: bacteria can&#8217;t nest on glass, reducing chloramines (chlorine odor).<\/li>\n<li><strong>Economical<\/strong>: glass washes faster, so you use less water for backwashing.<\/li>\n<li><strong>Doubled service life<\/strong>: 10-15 years compared with 5-7 years for sand<\/li>\n<\/ul>\n<p>The <strong>Calplas filter + AFM glass<\/strong> combination represents the very best in filtration. It is our standard for all new installations and renovations in <strong>Geneva<\/strong> and <strong>Vaud<\/strong>. <\/p>\n<h3>Our services: Changing sand or switching to AFM glass<\/h3>\n<p>Is your filter still working, but your water isn&#8217;t as clear as it used to be?  <strong>The problem probably lies with the filter media.<\/strong>  Over time, the sand becomes worn, rounded and less effective. Bacteria settle in, creating &#8220;preferential paths&#8221; where water passes through unfiltered. <\/p>\n<p>Our technicians are on hand in Geneva and Vaud to give your filter a new lease of life:<\/p>\n<ul>\n<li><strong>Complete emptying of<\/strong> old media (sand or used glass)<\/li>\n<li><strong>Inspection<\/strong> of tank, strainers and diffuser<\/li>\n<li><strong>Filling<\/strong> with Dryden Aqua AFM glass (or new sand of your choice)<\/li>\n<li><strong>Start-up<\/strong> and filter time setting<\/li>\n<\/ul>\n<p><strong>\ud83d\udca1 Tip: <\/strong>Take advantage of the media changeover to switch from sand to AFM glass.

Allow 5 to 7 years for sand, 10 to 15 years for AFM glass. Signs of wear: cloudy water despite correct treatment, increasingly frequent backwashing.    <a href=\"https:\/\/www.astro-piscines.ch\/en\/contact\/\">Ask us for a quote.<\/a><\/p>\n<p><strong>Why choose a Calplas filter over another brand?<\/strong><\/p>\n<p>Calplas filters are made from hand-laminated polyester, offering decades of durability. Unlike blown plastic filters, which can warp under pressure or UV light, Calplas tanks remain stable. It&#8217;s a very long-term investment.  <\/p>\n<p><strong>Sand or filter glass: which to choose?<\/strong><\/p>\n<p>AFM glass is superior to sand in every respect: filtration fineness (1 micron vs. 40), anti-bacterial properties, doubled service life. The initial cost is higher, but the investment pays for itself in water and product savings. You can find AFM bags in our <a href=\"https:\/\/www.aquastore.ch\/fr\/184-masse-filtrante\">aquastore.ch<\/a> online store or at our Nyon store: Route de Champ-Colin 2C.  <\/p>\n<p><strong>Is it possible to replace an old filter with a Calplas on an existing system?<\/strong><\/p>\n<p>Absolutely. We regularly replace tired filters with Calplas. Standard fittings (2&#8243;) allow easy adaptation. We check compatibility with your pump during our free diagnosis.   <\/p>\n<p><strong>What is the warranty on Calplas filters?<\/strong><\/p>\n<p>Calplas filters come with a 5-year manufacturer&#8217;s warranty.
