Seems insane. Is there some non-mold flex tubing available anywhere such
as Home Depot?

Run cleaner water or sanitize the tubing periodically. Tubing is just
providing a place for mold to grow. The spores are in the water.

True. It is probably not mold anyway. Algae is more likely, caused by
the light hitting the spores in the water.
