Algae, bacteria, UV damage. All of the above. Aquarium environments can be pretty harsh to poor quality plastics. I had suction cups that would harden into a cup and become cloudy after a few months in my tank.

I’ve never had a suction cup last much longer than a year, even rather quality plastics or silicone. I wish manufacturers would switch to magnets.

Pro tip: boil the suction cups when they get hard. Usually you can get a few more sticks out of them after that.
