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 ,
