We got the winter cover off our IG pool today, and the water is nice and clear with some dirt in the deep end, no problem there. However, around the edges and on the edge of the slope to the deep end, it looks like sand has settled there. It is light in colour so is not the usual dirt from the gardens around the pool. I am thinking it is sand from the filter. Thinking back to the last summer, I always noticed a "shadow look" to the pool and always thought it might be algae, but now I am thinking it was sand coming from the filter. I assume there is a problem with the filter, but I am not sure what to check or do about it. We have never changed the sand in the filter, so I am sure it is due for that. How do you go about getting the sand out of the filter? and what should I look for when we get it out?
Thanks!
