Waterfalls and other features can be designed as single elements flowing into a pool or a spa. They can also be constructed to flow from a spa into a pool. They can be constructed of natural materials (granite, limestone, blue stone, etc.), cultured stone or a combination of both.
QDP recommends Hayward and Pentair high efficiency equipment.
H Series Heater Electronic Ignition (80 - 82% efficiency)
H Series Heater Electronic Ignition, plus induced draft (84% efficiency)
Tri Star Superior Energy Efficient 1 or 2 speed
Tri Star Mizzer-variable speed, superior energy efficient
Master Temp electronic ignition, plus enduced draft (84% efficient)
Intelliflow - 4 times 160 high performance
QDP recommends and uses the following:
Healthcare or Superior Aqua
Ionization-Ozone Sanitation System
Replaces chlorine and kills bacteria
Chlorine salt generator system (generates chlorine from salt)
You do not need to buy chlorine.
Ozone generator generates ozone and bubbles up through the water to sanitize the water.
Diatomaceous earth media (DE).
Most efficient for water clarity, less operating time.
DE filters the water to one (1) micron.
Swim Clear cartridge filter.
Filters the water to ten (10) microns
Pro Series sand filter.
Filters water to fifteen to seventeen (15 - 17) microns.
