Intec CA10 Instruction Manual page 23

Test for pH.
Treat if necessary.
Takes less than 10
minutes
Total time is less than forty minutes a week. Water is always clear, blue, and very healthy.
NOTE: Wait for a minimum of 30 minutes after treating pool before allowing anyone to swim.
When treating your pool, make sure that you are running the pump and recirculating the water.
6.3 Pool Filters
6.3.1 Diatomaceous Earth (DE) Filter – This system will filter suspended solids from your
water down to 10 microns. This is very good; however, the DE filter will cause the TDS (total
dissolved solids) to increase. This increase will cause your treatments to work less effectively
and those treatments will take a little longer to take effect.
6.3.2 Zeolite Filter - (also known as Zeosand or Zeobrite) will filter your pool water down to
5 microns, which is even better.
The above two filters have one major problem. They both use a lot of pool water for
backwashing. The backwashing takes the water that you have been testing and treating out of
the pool. This requires you to refill the pool with untreated water thus changing your water test
parameters. Now you have to do your testing and treatment all over again to attain the previous
levels achieved before the filter was backwashed.
6.3.3 Cartridge Filter - This will filter the pool water to 20 microns and it requires no
backwashing. You simply take the cartridge out and clean it with a sweeper nozzle. The nozzle
is available at any hardware store. You have not changed one gallon of the pool water chemistry
and you do not have to retest and retreat the water.
Same as Monday.

Test pH and treat if
necessary.
Test alkalinity. Will need
to treat every five or six
weeks. Test copper and
treat as needed. Treat pool
for clarity. Less than 20
minutes combined.
