The Delta 1 Aqualizer magnetic water conditioner and lime fighter. Installed in line for 70% more strength. With two in line force fields. It stops algae without chemicals or maintenance.
As cold water passes through the intense magnetic field the characteristics of the water are changed so that algae will no longer be a problem and scale can not form on the inside of pipes or processors. It connects with a 3/4" MPT (male pipe thread), 20 GPM (gallons per minute).
