Great idea. I did it immediately and am so far finding no sand in the improvised trap! Now it would appear that our fairly new marcite (4 years) is disintegrating. Oh no! It cost a fortune. What could be going wrong? It appears that the marcite both above and below the winter pool water level is rough to the touch. It was so smooth and nice before this winter.duraleigh said:Find a way to get a nylon or something very fine over the returns into your pool. They'll capture the sand if that's where it's coming from. Good idea to find the source definitively and then find a cure.
The "white sand" is probably the scale. Your very high prior pH indicates conditions were very favorable for scale to form.If it is scale, how do we explain the white sand in the Polaris?
I just copied this and put it on my wife's desk, right under her nose. If I don't post for a month or perhaps disappear, you'll know it was not one of my better ideas!!OK. I humbly defer to Duraleigh then
