Filtration Duration Guidelines
Filtration is the first vital step in managing a pool. Good filtration (the filter and media in good condition and adequate filtration
duration) reduces the organic matter and nutrients in the pool water and allows for stable and predictable water treatment. Poor
filtration means that even high levels of chemical treatment may be unable to maintain the pool water in safe and healthy condition.
Water treatment (pH and disinfection) will only run if filtration cycles are programmed with at least one
4.4.4.5.1 Filter and Media
Ensure that manufacturer guidelines are followed for the chosen filter and media. Filter and filtration media in poor condition reduce
filtration efficiency and increase running cost, whilst risking health due to algae and bacterial growth. Renew or clean the filter media
periodically, as recommended by the manufacturer.
4.4.4.5.2 Hydraulic Coefficient
Adequate filtration depends on the hydraulic coefficient of the filtration.
Filtration Rate per Hour is the actual rate of filtered water returning to the pool.
In a correctly designed swimming pool, the hydraulic coefficient will be 4 to 6; a coefficient lower than 4 results in increased energy
costs and a coefficient over 6 can result in inadequate filtration. This coefficient can be compensated if above 6 by adding filtration
duration.
When calculating filtration duration in all automatic modes, PoolCop takes the hydraulic coefficient into account and adjusts the
filtration duration accordingly.
4.4.4.5.3 Timer Based Filtration
In TIMER mode, filtration durations are not managed by PoolCop but chosen by the end user who must then make sure to correctly
set the duration according to pool needs. A too long duration will waste energy and a too short one may not allow to keep the pool
in good conditions.
4.4.4.5.4 Temperature Based Filtration
In ECO+ mode, PoolCop uses measured temperature to calculate filtration duration. Duration is recalculated daily to optimize
filtration:
Significant savings are made in the off seasons by reducing filtration duration during the cooler months.
Increased water temperature requires longer filtration time. So, during summer the filtration time is increased, which is very
effective at eliminating nutrients which cause bacteria and algae to proliferate.
Pump (and other equipment) life expectancy is extended, as use and wear is minimized.

The filtration duration must circulate the pool water at least once during a day.

4.4.4.5.6 Continuous Filtration
With multi speeds pumps and especially when pump is running at low speed, it makes sense to set the filtration to 23 hours per day
in such a case, the filtration is not managed by changing the duration but by adjusting pump speed. In
