When to Call a Professional
Contact a pool professional if the Hi Salt error persists after proper dilution, if you're uncomfortable with draining/refilling procedures, or if you suspect equipment malfunction. Also call a pro if your pool requires more than 30% water replacement, as this may indicate a more serious issue.Frequently Asked Questions
What causes high salt levels in my pool?
High salt levels typically result from adding too much salt initially, not accounting for salt already in fill water, or repeatedly adding salt without proper testing. Salt doesn't evaporate, so levels only increase when salt is added or when water evaporates without replacement.
Can I swim in a pool with high salt levels?
While not immediately dangerous, swimming in water with very high salt levels (above 4000 ppm) can cause skin and eye irritation. It's best to fix the salt level before swimming, especially for extended periods.
How long does it take to fix the Hi Salt error?
The actual draining and refilling process takes 2-4 hours depending on pool size, but you need an additional 8-12 hours of circulation time before retesting. Plan for a full day to properly resolve the issue.
Will diluting my pool affect other chemicals?
Yes, adding fresh water will dilute all chemicals including chlorine, pH buffers, and stabilizer. Test and rebalance all chemistry after fixing the salt level, but wait until salt levels are corrected first.
How can I prevent Hi Salt errors in the future?
Always test salt levels before adding salt, add salt gradually in small amounts, and test your fill water for existing salt content. Keep a log of salt additions and test monthly during swimming season.
