Here is a pic of one of my tanks with an aquarium sponge used as a baffle. MUCH safer than the plastic bottle baffle, IMO. One of our posters here lost her curious betta when he swam into the water bottle, but couldn't get out. Poor thing drowned.
Not only is the sponge/foam baffle safer, but it gives the "good" bacteria another place to grow!
AND it's easy to control how much flow you want - pull it up for more flow & down for less.
