Question

Do I need a 220 line to run a 3/4 hp pump?

Community Answer

220 is more efficient than 120 and will help keep the energy usage lower. Run time depends on size of pool and hydraulics. Residential In-ground pools are generally hydraulically built to run 8 hours a day for proper turnover rate, with a temperature of 80 degrees. Every 10 degrees warmer than 80 degrees pump should be run 1 hour longer. For example, 90 degrees run 9 hours. This is for a single speed pump running 3450 rpm.

Question

How long should the filter pump run after the two 12 hour turnovers?

Community Answer

Let the filter rest for about a day, then run the filter in 6 - 8 hour intervals every day that you want to use your pool.

Question

My pool was clear while the sand filter was running, but when I scrubbed, the walls were green again. Any suggestions?

Check the balance of your water. It may just need to be super-shocked. Depending on the size of your pool, a bottle of vitamin C tablets could solve your problem. Just a note, know what you need before you go to buy your chemicals. Pool stores sell chemicals. It is how they survive.

Question

Is it correct that (2x10)/2 = 10, NOT 5? Also, should it be (2+10)/2 = 6?

Community Answer

(2x10)/2 = 10, because in the first part 2 x 10, this equals 20. We then divide it by 2, 20 divided 2, equals 10. (2+10)/2 = 6 is correct. 2+12 equals 12, then dividing 12 by two equals 6.

Question

Should I run my pool filter in the daytime or nighttime?

Community Answer

This answer is dependent on a few factors, like your neighbors and your power company's peak on and off hours. It's best to run your filter outside of peak hours to keep your electric bills in check. Noise ordinances in communities usually stop around 8 AM and begin around 10 PM, so check to make sure which ordinances you live under, if any.
