To help determine the size of pump needed for a particular water garden, calculate the volume of the pond in gallons using
the following formula:
L (length of pond in feet) x W (width of pond in feet) x D (depth of pond in feet) x 7.5 = pond capacity in gallons
It is recommended that the water be circulated at least once an hour. For example, a 4,000 gallon pond will need at least
a 4,000 GPH pump. Please note that ponds utilizing a waterfall or other water features should use a pump with 25-50% more
flow than the pond volume.

Aquascape introduces its RainXchange System for capturing, filtering and re-using rainwater. RainXchange combines a re-circulating
water feature with a sub-surface rainwater harvest storage system. The filtration captures, filters and houses rainwater run-off
for future use. The system also reduces flooding. Contact Aquascape Inc. at 630/659-2097 or jzuri@aquascapeinc.com

Hunter Industries
Hunter Industries offers an easy to install and change PGJ Rotary Sprinklers system with a water-efficient nozzle and easy
adjustment from the top of the sprinkler, and the safety and durability of a rubber cover. The PGJ is capable of working with
larger rotors to combine big and small areas in a single zone, offering a convenience and efficiency that most sprays do not.
With PGJ, few heads perform the work. The PGJ's interchangeable nozzles provide a wide and versatile range from the optimum
performance is based upon 40 PSI (2.8 bars; 275 kPa), dynamic operating pressure. The average precipitation rate is approximately
.60" per hour (15 mm/hr) for an 180¡ arc sprinkler. The actual precipitation rate may vary, and should be calculated. Contact Hunter Industries at 760/744-5240 or http://www.hunterindustries.com/.
