WATER MAINTENANCE
IMPORTANT: Your Caldera spa warranty excludes surface or component damage caused by poor water chemistry, the improper use or applica- tion of chemicals, or the use of
WATER PURIFICATION WITH OZONE (OPTION)
The Caldera Pure Water Ozone system produces ozone to “burn out” water contaminants, bacteria and viruses through the process of oxidation. Ozone is continually pro- duced and distributed to the spa during the filtration/skim/filter cycles.
Ozone does not replace traditional water sanitizing chem- icals such as chlorine or bromine. A small amount of chlo- rine or bromine will be needed in the water in addition to ozone. Ozone will be doing the major job of killing microorganisms and oxidizing bather waste such as per- spiration, body oil, suntan lotion, etc. The chlorine or bromine will be providing the measurable, lasting residual and preventing algae from growing.
DO’S AND DON’TS OF SPA WATER MAINTENANCE
DO read labels carefully and follow direction precisely. Though chemicals protect you and your spa when used correctly, they may be hazardous in a concentrated form.
DO add all chemicals slowly into the filter compartment with the Hydro jets operating in high speed.
DO handle all containers with care. Store in a cool, dry, well- ventilated place.
DO NOT use swimming pool chemicals in your spa.
DO NOT use household bleach (liquid sodium hypochlorine).
DO NOT allow anyone to be in the spa while chemicals are being added or dissolving.
DO NOT use incorrect products such as Trichlor, which has a very low pH (2.6), dissolves very slowly, is highly concentrated and was designed for concrete or plaster swimming pools. It will cause damage to your spa!

DO NOT use swimming pool (muriatic) acid to lower pH. Many swimming pool water care products can cause dam- age to spa surfaces and equipment.

SAFE
DO NOT splash pH “increase” additives on the redwood cabinet during pH adjustment. Many pH “increase” addi- tives will cause redwood to turn dark by pulling the tannin (reddish color in redwood) out of the wood.
