Why is it easier to grow algae in my tank than any live plants? I've got a
29G tank, which has all the essential/default equipment (filter, heater,
hood, light, etc), yet all the plants I ever put in there die within a month
or less. But meanwhile, the algae seems to thrive, and grows on all the
plastic plants and tank glass, and some of it on the filter intake tube and
gravel, but not on the heater.

Generally it means that something is out of balance. Post more
specifics about your tank (water parameters, how many watts of light,
etc) and people will be able to give you better ideas.

Offhand, the usual culprits probably apply - not enough light, and
need for CO2 injection.
