    Backwash Question

    So, I understand only backwashing when needed and agree with the concept why waste my perfect water.

    I am using a Polaris 9300 Sport and a Catfish handheld to vacuum, so i don't suck the dirt through my filter to reduce backwashing. My pressure has not moved since opening(brand new pool, clear water from the fill) and i used the regular vacuum one time for the first cleaning (lots of red dirt/clay, lots of small cement scale etc.). Is there a time frame when i should backwash or just wait until the pressure goes up, it has not moved since opening (around 4 weeks). I will be adding DE to the filter once i get the CYA totally in line, I am edging it upwards to not overshoot. If my filter pressure does not go up should i just wait until the end of the season or.. that is probably just wishfull thinking.

    A lot of people only backwash once a year. If the pressure doesn't rise and the flow doesn't decrease, don't worry about it.

    Wish I had that luck. lol. We've had a few dust storms this last week. My pool turns brown. It cleans up easy enough but I've backwashed 3 times in 10 days. HA!
