Well, after about a month of going nuts trying to get happy with the flow in my 29G (the ex-Garrett "muscle cube"), playing with Koralia Nanos, a Tunze 6025 (stupid mounts keep breaking... grrrr ) and not wanting to blow any more cash (or take up any more space) with something I won't quite be happy with... I bit the bullet, and ordered myself a Vortech MP20. I've seen some video of the MP20 on smaller tanks and was pretty impressed.

I can't wait to get it, and will post pics/video as soon as I can. Wish me luck!
