Do I have to add salt every month with a salt water chlorinator?
Salt should be added to the pool when necessary. Salt level may decrease after a heavy rain, backwashing, refilling, draining or excessive splash out.
Note: The salinity or salt level should always be tested before salt is added to the pool.
Do I still need to use granular chlorine with my Salt water chlorinator?
The salt water chlorinator replaces the hassle of having to use granular chlorine. If the chlorinator is the correct size, then it's sufficient to sanitize the pool without adding granular chlorine.
How do I add salt?
1. Turn on pump to circulate pool water.
2. Turn the chlorinator off or reduce the chlorine production percentage to zero.
3. Determine the amount of salt necessary to add from an appropriate chart.
4. Broadcast or spread the salt into the outer perimeter of the pool, or into the shallow end of the pool for quick and even distribution.
5. To avoid clogging the filter or damaging the control center and pump, do not add salt through the skimmer, main drain, or surge tank.
6. Brush the pool bottom and allow water to circulate for 24 hours to dissolve salt completely and mix evenly
with the pool water.
7. After 24 hours, verify correct salt reading.
8. Turn on the chlorinator or increase the chlorine production percentage.
Note: For a new pool or newly resurfaced pool it is recommended to wait 14 days (surface should be completely
cured) before adding salt. Follow the pool surface manufacturers guidelines for your particular pool. For vinyl
and fiberglass pools, salt can be added at start up.
Is it possible to use salt water chlorination when the pool liner is in natural stone?
Natural stone liners or ornaments may be more susceptible to blemishes and erosion when using pool water treatments. Natural stone can be visually altered over time. This can usually be prevented by sealing the stone with a sealer.
In the case of a salt water chlorinator, the salt may damage the stone along the water line over time (crystallization). We cannot guarantee the life span of this surface in the long term.
Is it true that a salt water chlorinator provides chlorine-free water?
No, a pool treated by salt water chlorination is a chlorinated pool in which the chlorine is produced automatically. The salt under the effect of electrolysis, is transformed into sodium hypochlorite, a disinfectant.
Is it true that salt water chlorination is maintenance free?
While the salt water chlorinator prevents the user from needing to add chlorine to the pool on a regular basis, some maintenance, in regards to water balancing, will still need to be accomplished.
Check the water balance as usual. The water balance will be less threatened, because only pure chlorine is added to the water. All other forms of chlorine (tablets, powder, liquid, etc.) contain additives. In addition, chlorine levels can be stabilized easier with less dramatic fluctuations.
My pool is currently treated using bromide. Can I switch from bromide to salt water chlorination using the same water?
If there is still a large amount of bromide in your pool, we recommend that you wait for it to dissipate. It is ok to startup the chlorinator when there is a little bromide in the pool.
The remaining bromide in the pool will produce a white emulsion (chemical reaction). The remaining bromide will not harm the users, pool equipment or the pool.
There are beads at the bottom of my pool, what does it mean?
The mineral purifier cartridge may have ruptured. The cartridge must be replaced.
What is polarity inversion on a salt water chlorinator?
Polarity Inversion is what salt water chlorinators use to periodically remove scale from the electrode plates. The controller will periodically change the direction of the cell current in order to eliminate the layers of scale that deposit on the electrode plates. This action maintains the cell. For very hard water, some chlorinators can shorten the polarity inversion time (e.g. 2.5 hours instead of 5 hours) so that the electrodes are cleaned more often.
Warning: shortening the polarity inversion time can wear the electrodes more than usual. This is why changing this parameter is reserved for the pool professional.
What type of salt needs to be used for salt water chlorination?
1. The purer the salt, the better the life and performance of the electrolytic cell. Use a salt that is at least 99.8% pure NaCl. The preferred salt is an evaporated, granulated, food quality, non-iodized salt. Consult your salt supplier.
2. Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS or yellow prussiate of soda) that could cause some discoloration of fittings and surface finishes in pool.
3. Water conditioning salt pellets are compressed forms of evaporated salt and may be used. Water conditioning salt pellets take longer to dissolve.
4. Do Not use calcium chloride as a source of salt. (Use sodium chloride only).
5. Do Not use Rock salt (insoluble impurities mixed with the rock salt can shorten the life of the unit).
When should I add salt?
Salt only needs to be added when necessary. This may be necessary after heavy rains, backwashing and refilling, excessive splash out, etc. It's always important to test the salinity before adding salt to determine how much salt should be added.
Will salt from the salt water chlorinator deteriorate the metal components in my pool?
If the ladder is bonded properly to the rest of the pool equipment, corrosion will be minimal. Most cases of corrosion can be better explained by an incorrect water chemistry as opposed to the presence of salt.
Stainless steel is better adapted to resist salt than Galvanised steel. If corrosion appears in one year, it can be explained by incorrect water chemistry or bonding issue, not by the presence of salt alone.
Will there be any harm if someone swallows salt water in a salt chlorinated pool?
While the salt shouldn't have any effect on the person if a small amount is swallowed, please keep in mind that the water is chlorinated and chlorine should not be consumed.
