Hi All
I had a lovely clear pool THEN the one way valve to the ballast tank got jammed with debris and the ballast tank back filled to overflow until pool and tank levelled out not a problem, cleaned the valve not a problem, refilled the pool, not a problem, ballast tank now too low to use, not a problem, just filter the pool via the main drain until water is tanked in. Now I have not used the main drain for approx 3 months and it has been very breezy and a lot of dust in the pool which has been vacuumed regularly, not a problem, except the dust accumulated in the drain. This is now in my pool and is proving difficult to remove even with flock. The moral of the story use all of the pipework on a regular basis.
