Reverse Osmosis/Diatamaceous Earth

[piratelady]

Glen that is a diatomaceous earth pool filter. I have one just like it on my pool. There is a pump in front of it the water runs through the filter and then back into the pool. I have to backwash it and then add more DE about every 2 wkks. Once a year we take the whole thing apart and clean the permanent filter inside because it gets caked with DE and doesn't work as well.
If you have any questions regarding the DE filter let me know. I have been dealing with them for about 30 yrs now.
