When would you use recirculate on pool filter?
In respect to this, why would you use recirculate on pool filter?
Reviewing Recirculation The recirculate setting on a swimming pool filter is actually used to bypass the filter mechanism. Recirculate allows the water to flow out of the pool and back into it again without running through the sand or diatomaceous earth in the filtration system.
Subsequently, question is, can you shock a pool on recirculate? Shocking The Pool With Powdered Shock Using “Re-circulate”: Once you start slowly pouring the shock into the skimmer, the shock will go into your pump and then back out of your swimming pool return jets.
Also Know, should you run your filter when you shock your pool?
It's best to run the pool filter for 6-8 hour before shock treatment, and to schedule the shock when the sun has set. Performing pool shock treatment will lower the potency of chlorine, making you use either twice as much chemical, or render your shock treatment ineffective.
What setting should pool filter be on when vacuuming?
For routine vacuuming, the filter valve is left in the normal “Filter” position. This directs dirty vacuum water through the pool filter to remove the contaminants, then conveys filtered water through return lines back to the pool. The "Filter" setting is used for light to moderate levels of pool sediment.
