Pool tools
Four calculators, each showing its own math. Estimates only — always confirm against your equipment manuals and product labels.
- Pool Volume CalculatorEstimate how many gallons your pool holds from its shape and dimensions.
- Pool Salt CalculatorWork out pounds of salt needed to move from your current reading to the target in your chlorinator manual.
- Pump Energy Cost CalculatorEstimate daily, monthly and yearly pump running cost, and compare two run profiles.
- Flow & Turnover CalculatorConvert between flow rate in GPM and the time for one full turnover.

- Why Is My Pressure-Side Pool Cleaner Not Moving or Getting Stuck?Start by identifying the exact pressure-side cleaner and how it is powered. Verify the filter system and any required booster pump are running, then check the model's feed-water path, screens/filters, hose, jets and backup mechanism. Jandy's current Ray-Vac support lists the filter system being off, a normal backup cycle, dirty finger/energy filters, a hole in the hose, a backup Hydro-Timer fault and a plugged transporter jet among causes of a cleaner that stops moving. Polaris/Fluidra also maintains separate troubleshooting for its pressure-cleaner models because the parts and backup systems vary.
- Why Does My Robotic Pool Cleaner Stop Mid-Cycle?Separate a normal completed program from a cleaner that stops early with an error. Check the model's selected cycle or mode and any status light first. Current Maytronics Dolphin troubleshooting for a cleaner that starts but fails to complete a cycle checks whether the power supply shuts off, then routes owners through a power-supply restart, impeller debris, tracks/brushes and visible obstructions. Cordless models add battery/charging and model-specific modes. Do not assume an early stop means the motor has failed.
- Why Won't My Robotic Pool Cleaner Climb the Walls?First confirm that the cleaner model is designed to climb the pool's walls and surface. Then clean the robot's filters, inspect its brushes/tracks or other traction components, and check whether algae or biofilm is making the wall slippery. Current Maytronics Liberty support lists clogged filters, incorrectly fitted filter panels, wall biofilm/algae, water balance and the model's operating-temperature range among wall-climbing checks. Use your cleaner's own manual for coverage and temperature limits; do not copy a Dolphin-specific number to another brand.
