What water conditions are recommended for my Dolphin?
Short answer: Use your Dolphin in balanced water at 43–95°F, keep salinity at or below 5,000 ppm, and wait 24 hours after shock or flocculant treatment.

The answer
What to know.
Keep your pool chemicals balanced before running your corded Dolphin. Unbalanced water can reduce cleaning performance and cause the robot’s components to wear out early.
Too little chlorine can allow small algae deposits to clog the filters and reduce motor power. If the pH is above the recommended range, the robot will not climb the walls.
After shock or flocculant treatment
Wait 24 hours after a chemical shock or flocculant treatment before returning your Dolphin to the pool.
Recommended water conditions
Use your Dolphin in water between 43–95°F. Below 59°F, wall-climbing performance may be reduced.
Water chemistry or temperatures outside the recommended ranges can interfere with operation and lead to early wear.
| Parameter | Recommended range |
|---|---|
| Alkalinity | 80–120 ppm |
| pH | 7.2–7.6 |
| Calcium Hardness | 150–250 ppm |
| Chlorine | 1.0–3.0 ppm |
| Cyanuric Acid | 30–50 ppm |
| Algaecide | 30–50 ppm |
Saltwater pools
Your Dolphin can run in a saltwater pool. Keep salinity at 5,000 ppm or less. Rinse the robot with tap water after every cleaning cycle to help prevent buildup.
