Perform-Max™
Thank you for choosing the Perform-Max Pool Sanitizer for you pool. Perform-Max precisely meters chlorine at a consistent
rate so you are ensured of a properly sanitized pool with less work and more time to enjoy.
Swimming Pool Tips
1. Before beginning with any
pool care program, you must
first balance your pool water.
Take a water sample to your
local pool professional or
use a complete test kit that
will test for the following
important elements.
2. If your fill water is high in
metals, use a sequestering
agent or metal-out product
at start-up. See your local
dealer for details on using
these products and always
follow manufacturer’s direc-
tions carefully.
3. After your pool is up and
running smoothly, continue
to test your water for pH,
total alkalinity and chlorine
and maintain its balance by
adding any necessary ad-
justment products (see your
dealer for details).
5. Shock the pool with
chlorine to rid water of all
contaminants before begin-
ning. Follow manufacturer’s
directions carefully. This
step is very important to
start-up. Use chlorine shock
only.

Water Balance Guidelines
Free Chlorine: 1.0 - 3.0 ppm
Free Bromine 2.0 - 5.0 ppm
pH: 7.2 – 7.8
Total Alkalinity: 60 – 120 ppm
Calcium Hardness: 150 – 400
Total Dissolved Solids: <1500
Stabilizer: 20 – 80 ppm
Do not add
shock in or near
the skimmer or
into the Perform-
Max as it could
damage equip-
ment, risk poten-
tial explosion or
discolor your
pool surface.
4. Add a stabilizer or con-
ditioner to the pool at the
beginning of the season if
the stabilizer level is below
20 ppm. This will prevent
chlorine burn off. Follow
manufacturer’s directions
carefully.
