Askyli 2.9lbs Pool Filter Balls for Sand Filter, Reusable Pool Sand Filter Balls, Efficient Eco-Friendly Blue Filter Media Balls, Suitable for All Sand Filter System (Equals 100lbs Pool Filter Sand)

I have had these in my sand filter for three years now. Before I was using sand ,we always had sand in the pool no matter how we adjusted the level.We installed these and experienced better filtration , and lower pump pressure with much higher flow. Which in my mind equates to more water being filtered. Now with that said I have noticed that the muck they filter plugs the filter balls up when left through the winter and back flushing won’t clear them up.So every spring I take them out of the filter place them in a netted laundry bag and run them through the wash machine with no soap and just cold water ,they come out like brand new and the filter works fine for the whole season.

I ordered 2 of these so that I can have some for my sand pump while im washing the old ones. I love that I dont have to deal with sand. These helped take my pool from looking like a swamp to just the most crystal blue I have ever seen

Great for sand filters, especially if youre on a well. This easily filtered out the iron and manganese in my pool water. This (paired with a vevor sand filter pump) was able to turn my 12000 gallon pool that had was brown/orange due to metals in the water. Beats the old bucket method.

We have a sand filter and have always had some sort of sandy residue in our pool. We decided to try that, as we heard they work better than sand. These little fluffy balls are amazing! Our pool has never been more clear! We have been swapping them out every 3 weeks. Never going back to sand again!!!

Love this product. Lightweight easy to clean and very easy to use.
