Depends on the size of your pump and the restrictions that are in the system, but usually 8 hours should be adequate if you have a 1.5HP or larger pump and a decent sized filter. If you notice that the pool is loosing it's sparkle you can always increase the time. Pool Masters
Usually the filters you can buy will specify what size (in gallons) the filter is meant for.
1 HP is fine.
The length has to be 50m and the width has to be 25m to be an Olympic size swimming pool. An Olympic size swimming pool also has to be at least 2m deep. So a minimum volume of 2500m³, which equates to 2,500,000 L (550,000 imp gal; 660,000 US gal).
Depends on size of pool but in a Olympic swimming pool 2,500 m3 (88,000 cu ft) or 2,500,000 L (550,000 imp gal; 660,000 US gal) minimum, depending on depth
No. Leave your filter running at least 8 hours per day, longer if your pool appears cloudy.
You would probablly be better off with a boiler
3000 gal tank pool
About 100 pounds of pool salt
how long will it take to fill a 3998 gal above ground pool, with a standard water hose
