My screens are not typical of what people use. I use the reverse side of wall tiles which have a rippled imprint on them. I scrape the entire surface of the tile each time, usually with an old credit card but occasionally with a box knife blade, when it starts to get quite tough. Obviously some of the algae is left in the ripples on he tile surface and I find that's easily enough.Originally Posted by TankTinkerer

It's not just me who runs with a scrubber alone.
