Water filter for (small) pool

The filter inserts for pool water filters are simply too fast. The best is synthetic coarse filter mat, which can be optimally cut and easily fixed with a rubber and is simply rinsed with warm water as needed. Important is the daily circulation, 2 to 3 hours are enough. The tanning burr of the filter fabric is a matter of experience. Who of course has the coal, can afford a new paper filter insert weekly. That's all money making!
