Curved acrylic algae scraper recommendations

[MFoley]

Hiya

Can anyone recommend algae scrapers for curved acrylic or glass at a stretch

I’m working on a project that I will post in Journals that uses vacuum pillars to pull water above the surface of the tank into 150mm acrylic tubes 40mm higher than the surface - see photo. It’s a work in progress.

I anticipate challenges cleaning algae in the pillars.

All recommendations welcome.

Morning The first thing that comes to mind is to use a babies bottle brush or a washing up brush as they are softish and some are slightly curved at the end.
