Here's a video of what my WP-40 does in my 220g. I do have some korallias in there, but none of them are on any wave controller. [video=youtube;P6JmgjLEzIw]http://www.youtube.com/watch?v=P6JmgjLEzIw&feature=youtu.be[/video]
Im getting in on it. Just trying to determine how many 40s I need and if I need a 25. Also these are coming with the new controllers that have a speed options, so no longer need the additional power supply to lower the speed
