AlphaONE LH Pond Filter Features:

Even though the AlphaONE is regarded as the least restrictive filters on the market, GC Tek has found a way to imporve even more.  Most of the restriction with a pressurized system comes from the Multiport valve.  On the AlphaONE LH the water bypasses the Multiport valve on the regular filtration mode and only travels through the Multiport valve on the "Backwash" mode, thus giving you the least restrictive filter available.  On the AlphaONE LH, CG Tek reworked the internals slightly for even greater flow through.  This allows the use of a smaller, lower amperage pump to move the same amount of water.  The AlphaONE LH was designed for the pond keeper that has energy efficiency as a top priority.
