Intex Krystal Clear sand filter system
Question about Intex Krystal Clear sand filter system
When vacuuming the bottom with the lever in the "Filter" position, the same greenish soup is pumped out of the outlet and into the pool. I have filled it with quartz sand
Helpful answer
The following could be the case: Dirt is so fine that it passes through the sand. Then you would have to add flocculant. It binds the finest turbid substances into larger lumps so that they can be caught by the sand. However, you need extremely fine turbid matter for the sand to no longer work.
