I installed a new Triton II (TR100). I checked that the laterals were hand tight as per the installation manual and was careful putting in the pea gravel and pool filter sand not to damage them. The filter has been running for about 3 days with a Pentair Whisperflo. The water got sparkling clear very quickly which is good but there is about a half pound of sand accumulating in the bottom of the pool under each vent every morning. I vacuum the sand with a shop vac so that it doesn't return to the filter. Could this sand just be the particles too small to get stopped by the laterals and will eventually subside??? Thanks.
