Just come back to Cyprus after three months away at the hottest time of year. The pool had a solar cover on and the filter was set for about four hours a day. We thought that someone we had asked to look after it would occasionally hoover it etc, but it seems that all they did was to drop in chlorine 3 in 1 tablets.
Now we are trying to clean it up. We had a sandstorm just to make things worse. The water is murky and had a greenish tinge. The Ph was non existent so I am adding some Ph Up in the skimmers most days and it has at least reached the bottom reading on the testing kit. Chlorine seems okay.
My problem is that when I switch on the pump prior to backwashing (yet again) a stream of filthy water goes straight back into the pool through the three filter outlets. How can I get rid of the dirt which has filtered without half of it going back in? What would be the best regime to follow to get the pool clean and sparkling once again? Step by step would be appreciated.
On the bright side, the green tinge has now gone, following the discovery that the sand in the filter was very low and we topped it up. However, I haven't seen the bottom yet (after ten days). I would love a swim - it is very hot......
