I think I saw this happening with regular water as well. The conditions were: Several algae farms freshly constructed In a flat area that was slightly flooded with dripwater Near a basin The dupes were trying to pick water off the floor and feed it to the algae, but not making progress. The problem cleared up after save/restart/load.

I captured a video of this bug happening. I also have a save game manifesting it (attached). why algae not work.7z

Do you have a game pad plugged in? I haven't tried it with ONI but I've noticed that can happen with other games (X-COM 2) simply due to having a joystick plugged in.

Actually I think what might be happening is that they're trying to suck up the contaminated water, but there is no "contaminated bottled water", so they end up carrying nothing.

Sometimes my duplicants try to water algae farms with nearby contaminated water. The contaminated water immediately spills off the algae farm into the pit that the dupes got it from, with the result that they appear to get stuck in a loop of continually sucking up and spraying water to no effect. I'll try to attach a video of this happening. bugreport_contamwater.mp4
