My pump has been running for 10 hours a day and after reading a few posts I have scaled the pump down to 8 hours per day. Additionally I am having my water tested by the pool company every 7-10 days. There are barely any leaves that enter the pool so the pool stays pretty clean as in the morning with the pump off the water looks crystal clear (good news). The pump PSI is about 10-12 on a normal day (it used to be higher @ 15 PSI) and now has changed. I was told only to backwash after the pump increases above another 10 psi. After reading a few posts I understand that backwashing should be done when there is a 25% increase in pressure. I will swap out the gauge as sometimes water enters the gauge and then dries up to make sure I am getting an accurate reading.
Q: Should I go back to 10 hours a day or leave @ 8 hours per day or even less.
Weekly I add approximately 1.5 lbs. of non-chlorine shock (alternate 1 lb. and 2 lbs.) weekly
Weekly I add a capful of Commercial Strength Phos-Free to the skimmer basket and if we have heavy rain I will add 2 capfuls
The Setting on the Frog System is 5 and the chlorine packs last about 9-10 days before they have to be replaced.
Outside of this every few weeks I have to add 5 LBS. & 9 LBS. OF EZ COLOR ALKALINITY UP and in the beginning of the season I had to add 15 LBS. & 11 LBS. OF EZ COLOR CALCIUM HARDNER & some 1 Gallon of Water Conditioner. Also the BAM 90 Day Algae protection was ran through the system about 2 months ago.
My pool had to be opened up super early as the soil needed to settle before the concrete was poured.
Should I modify, adjust or change anything that I am doing? What could have caused the pressure drop reading on the gauge? So far no problems. I also backwash about every 3 weeks and fill the pool with some new water.
