    CYA level

    I have a 32K gal inground vinyl pool. 3 weeks ago I took a water sample to the local pool store for analysis. They said the CYA was 171 and that I needed to drain and refill 70% of the water. I am on a well system so that is not possible without having water hauled in. So, I set up a...

I am planning to switch this 200 sq ft filter out for a 425 sq ft filter but I wanted to find out roughly how long I should expect the filter to last between cleaning. Even though it is undersized shouldn't I get a week out of...

    Frequency of cartridge filter cleaning

    I purchased a 200 sq ft cartridge filter system 2 months ago that is suppose to work for in-ground pools up to 49,000 gallons. The purchase was to replace my 20 year old DE filter system. My pool is 32,000 gallons and the water is staying well balanced and very clean. Currently I am having to...
