hello all, long time no post on here but thaught i had something to ask. is it posable (to anybody in the uk) to get different coloured pond liners ? i am going to increase the size of my pond at the end of this season and thaught a light grey liner would look nice and brighten the pond up a bit instead of black ? searched online and cannot find anything, just black. also i wonder why such a lack of colour options, why are they always black ? is there some reason for this ? thanks
