yea that was me with the sand issue...still havent figured it out...i have changed thermostats,heat sensor switches...pulled and flushed heads/powerhead, new waterpump and impeller...still overheats.....i bought a laser thermometer and was able to figure out which cylinder was over heating.....i then pulled the thermostats out and it runs 30 degrees cooler on that cyl on the hose, i havent been able to run it in the water yet.

sure hope yours is easier to find than mine has been.
