I keep getting a lot of algea on my glass, even after faithfully
and once a week water changes, once a month complete water
change and "scrub". I have a plecky, and I was wondering using
a algea destroying or treatment will hurt the pleco in my
cichlid tank.

The active ingredient in almost all anti-algae chemicals is the
herbicide simazine. However, this only controls certain types of
algae and has also been shown to stunt the growth of the young of
certain species of fish. Do a Google search for simazine if you
want more information. I tried it once, and do not recommend it.

As others have suggested, it is also generally not recommended to do
a "complete water change". Partial water changes are recommended to
prevent shocking the fish by making too abrupt of a change to their
water conditions.

Bristlenose plecos are most often recommended for algae control in
rift lake cichlid tanks. You might try one of those if you have
some other species.
