OTHER POOL FILTER Bug

1. My filter needs cleaning or backwashing besides oft

When the filter is brand new, one might expect a filter cycle to last thirty days or longer between cleanings. As fourth dimension goes by, the filter media (DE powder, filter sand, or the filter cartridge) breaks down and or clogs up, and may point that it's time to change the filter media. If you find yourself having to aftermath your filter every week, you probably demand to supplant the filter media, assuming that your filter is properly sized.

Generally speaking, filter sand will last v-7 years earlier the sharp edges become rounded, resulting in less constructive filtration. DE filter grids can last longer, seven-nine years before the textile breaks downwardly and develops holes. And your puddle filter cartridges volition only last two-four years, depending on the work it has been asked to do. Eventually, all filter media will demand a replacement, and a good indicator of when to change it is the length of your filter cycle.

2. My filter is not keeping my puddle water clean and clear

Are the pump and skimmer baskets clean? Is the water chemically counterbalanced? And the biggest question of all: Is the filter properly sized? If the answer to all these questions is yep, refer to pool filter trouble #1 above. The filter media may need to be changed.
