While I had my sand filter apart, I decided to top-up the sand to make up for what I had wasted. My pool store sold me a "mineral replacement"
They told me this was better than sand - because it would last longer, would filter down to 15 microns, it didn't have silica dust - it was $14.99 for 50lbs so I bought it.
So at home I googled it ...
.. Its made by recycling mining tailings....
its Technical Information
• Grain size 0.850 to 2.25 mm
• Grain shape Semi-angular
• Filtration capacity 15 microns
I think this is not what I should I be using in the filter because these particles are too big.
From the owners manual the grain size called for is
1. Wedron Silica/Best Sand Co., Sand Grade: Wedron .45-.55mm., Effective Size .46mm, Uniformity Coefficient 1.22.
2. U.S. Silica - Silurian Filter Sand, Sand Grade.45-.55 mm., Effective Size .48mm, Uniformity Coefficient 1.18.
The closest I can find to that specification is.available from a hardware store.
TEMISCA FILTRATION SAND and is profiled as
47% mesh 20-.85mm
47% mesh 30-.60mm
6% mesh 40-.425mm
Am I jumping off the deep end if I return the product to the store and tell them selling this is a disservice to there customers?
Is the Temisca sand much closer to what I should be using?
Am I getting my shorts bunched up over nothing?
