I noticed some white granules that look like salt on the steps of my pool near where a water inlet jet is. When you attempt to scoop them out with a net they almost turn to liquid and dissolve away.
I have a Aqua Rite Salt Chlorinator from Goldline that is now about 4.5 years old and I've had to turn up the output to around 100% to keep up with high summer temperatures and CL. I have even added a few chlorine tables on occasion when the temp is at 110 or so, but I've never seen this problem over the past 4.5 years.
After seeing the problem I decided since it appeared to come from the jet that I would check my pool filter to see if there was any build up there. Wow was I surprised. My filter (Cartridge) was full of the stuff!! The bottom of the filter must have had 6" solid of this white salt-like stuff. I drained the filter and was able to just scoop out handfulls of it.
My pool looks very clean and clear, except I have noticed that sometimes you can see small particles/flakes in the water, especially at night with the light on.
I haven't taken my water to anyone for testing just yet, but my chlorine and ph are fine. I've never added anything other than acid to my pool or ph and shocked once a month or so.
I would love any input you can give me.
