Emperor UV 130 watt 3" body - Filters up to 17,100 gal

The Emperor Aquatics Smart 130 watt UV Sterilizer will keeps ponds up to 17,100 gallons crystal clear. Smart UV Sterilizers are guaranteed to turn green water crystal clear in 5-7 days by inactivating waterborne algae blooms and harmful waterborne pathogens. By using ultraviolet light to specifically target these problematic microorganisms, you not only get crystal clear water, but you also protect your fish from diseases like KHV (Koi Herpes Virus); helping them to reach their full color and growth potential.

Important:  UV Lights have flow rates. For maximum effectiveness in the control of green water be sure to create a bypass. Visit our Pond Library for a "How to Create a UV Bypass" diagram.

Small to Moderately Sized Ponds (up to 5,000 gallons) using Skimmer and Falls
This is a very popular filter system style. Placing the UV Sterilizer between the skimmer box and the bio-falls filter ensures that pre-filtered water reaches the UV Sterilizer, increasing its performance while reducing maintenance. Often the capacity of the pump exceeds the capacity of the UV Sterilizer, if this is the case, install a by-pass manifold. Be sure that the skimmer is equipped with mechanical filtering (solid waste removal) capacity

Larger Sized Ponds (above 5,000 gallons) Surface Skimmer/Pressurized Filter
This is a very popular filter system style. Placing the UV Sterilizer between the skimmer box and the bio-falls filter ensures that pre-filtered water reaches the UV Sterilizer, increasing its performance while reducing maintenance. Often the capacity of the pump exceeds the capacity of the UV Sterilizer, if this is the case, install a by-pass manifold. Be sure that the skimmer is equipped with mechanical filtering (solid waste removal) capacity.

The SMART UV Sterilizer is positioned after the mechanical filter where it can receive only solids-free water, optimizing UV transmittance/performance. Notice the three-way valve that regulates suction from the skimmer and drain to the pump, allowing flow control. Next, multiple "clean water" returns improve circulation in the pool suspending solid waste helping it to find the filter. If you have a flow rate that exceeds the UV Sterilizers, install a by-pass manifold (see diagram #2).
