I wouldnt use any checmicals.....but with spraying them off with the garden hose, it will make a difference....it just takes patients, and you will need to do it more than once. Also a mild soap solution {like dishwashing liquid deluted with water} in a spray bottel, and then wipe the leaves, so it doesnt go into the water will help as well....BUT I would first try using the garden hose.....non toxic to the fish and it will help..... Good luck!
