COMMON MECHANICAL
OR POOL OPERATING ISSUES
Cartridge Filters: NOT COMPATIBLE
They don't receive a regular soak in chlorine and form molds and biofilms
and are not compatible with the ECOsmarte system, when total gallons of
water exceed 1,000. They are used on spas only.
Sand Filters
At least a 200 lb Sand Filter is needed for the necessary filter bed depth.
200 lb filter will not support a 1.5 hp or larger pump -- see The
Comprehensive Guide to Swimming Pool Ownership at
www.ecosmarte.com/pool_request.html.
Zeolites holding phosphates
Annual acid wash is required along with checking the bed depth in the filter
if ZeoBrite is used. Most other zeolites are incompatible as they pull calci-
um hardness and copper from the pool. All Sand Filters require media
change-out every 3 years, zeolites as needed. Consider Glass Pack®.
Keeping the Pool clean
Suction vacuuming and/or wall brushing is needed weekly during high sea-
son with all heavy vacuuming done to WASTE. As with chlorine pools,
water will not be clean for 48 hours after heavy vacuuming or if skimmer
baskets are full.
Backwash: Timing & Method
Sand, Glass or Zeolites: At 6 to 10 lbs rise in filter pressure backwash
for 2 1/2 minutes, followed by a Rinse to Clear Sight Glass (seconds). Turn
off pump and REPEAT backwash and Rinse. A 5 minute backwash will
leave algae spore in the filter. Glass filter to backwash at 6 to 8 weeks if no
pressure rise has occurred.
D/E or Perlite: At 10 to 18 lbs pressure rise on the gauge backwash for 2
1/2 minutes followed by a Rinse to Clear Sight Glass (seconds). Turn off
pump, repeat twice.
