Finally, 9 months after opening my new pool, I did a backwash for my sand filter. I switched off my pump and turn my filter selector to backwash and power on. The water is not that dirty but very murky with sand. After running almost two minutes, the colour improved to yellowish and almost clear. I switch off the pump and turned my filter selector to rinse then back to filter position. Then I turn the pump and and to my horror, out came murky water into my pool like a gaint squid sleeping on mud being disturbed.
It's been so long since opening and without ever doing it before (backwashing) and not finding my instruction manual on how to backwash, I just seems to lost control. Having started at this forum as a complete newbie early this year, the many gurus and taught me how to manage my pool and I would say they did an excellent job because by just following their directions, my pool had been sparkling since then without a single problem. Now I have to come bck with this foolish problem.
Where did I go wrong? Or is it that I did not rinse my sand enough during initial installation?
