Thread: Removing ' Water Level' dirt/discolouration ?

    Removing ' Water Level' dirt/discolouration ?

    Advice please !

    We have a fibreglass pool . Our previous pools have all been 'traditional' pools with 'plastic' liners.

    I have great difficulty removing the staining at the water level around the sides of the fibreglass pool.

    I have the PH/CL levels correct.
    Our water is NOT high in calcium.

    I have tried the usual products .

    What would you guys recommend please ? Is this usual with fibreglass pools perhaps ?
    Our older 'traditional' pools [ with a liner ] were much easier to clean.

    Much obliged for any advice ,

    Thanks ,

    A Mr. Clean Magic Eraser and a Scotch Brite pad usually get it done quite nicely.
