I have a 20' X 40' in-ground pool with a 4' shallow end and a 12' deep end.
How long each day should I run my pool pump?
I use powdered chlorine.
Answer
I run mine about 12 hrs per day, for a similar sized pool and 2 HP Challenger pump. That amount of time is sufficient to keep the pool sanitary, well mixed (no hot or cold spots), and for the skimmers to catch most of the floating leaves etc.
I run my Polaris (automatic cleaner) about 4 hours per day as well. It gets the crud that falls to the bottom of the pool.
While it's true that pool pumps are designed to run continuously, running them more than necessary chews up a lot of electrical power (a 2HP pump costs about $5/day or $150/month to run continuously; cut the run time to 12 hours per day and you save $75/month) and reduces the ultimate life of the pump and especially its motor (motor replacement for a 2 HP/240V can be $300 or more).

Are little bubbles supposed to be coming out of a sand filter on a swimming pool?
Beto24
On our swimming pool, little tiny bubbles are coming out of the sand filter. Is this normal? it looks like when someone spits on the ground, those kind of little bubbles. Is this normal?
Thanks
the bubbles are coming out in the pool from where the pump returns the water back into the pool.
Answer
Bubbles out the pool returns generally indicate one of two things.A suction leak or an obstruction in the suction line. First things that you can do.
1/ A small suction leak. Check the incoming plumbing connections to your pump. Also check the drain plugs on the front end of the pump to make sure the gaskets are ok or the teflon tape is fine and that they're snug. Check the pump lid gasket to see that it's properly seated and not damaged. If it's cracked it's time to replace it.
If you use an automatic cleaner that relies on being hooked up to the skimmer, check the hoses and connections for it for leaks. While you're at it, check to see if it's tried to eat something it can't swallow. A twig caught in the cleaner head can cause cavitation as the water rushes around it and be the source of a little air as it literally beats gas out of solution.
2/ Time to call a pool tech.
There may be something stuck in the pump's impeller blades or the pump's volute may have a faulty gasket between it and the pump body. The shaft seal may also be leaking. Water dripping under the motor with no obvious source, is a dead give away for this. There may also be a slight suction leak between the equipment and the skimmer. If this is an above ground, an easy fix, but if an in ground pool a tech is your best bet.
One last thing that's possible but unlikely is that the suction line has too many 90 degree elbows too close together in the line. This can cause cavitation as the water changes course in the line.
