I made a mistake on the Ehiem it's 3000 liters per hour, not gallons. It's only 400-800 gph
After some bargaining on the price and research on another forum, I decided to make the giant leap for 2 mp10wES. I'm getting them at cost (amazon price+international shipping rates) without the import tax. So i figured it wasn't a bad deal. I'd only do better if someone flew over and physically brought them to me. They'll be here tomorrow or the next day.
Several 28-35g owners on another forum had expressed their desire to have a second mp10 in their tank. I think that really persuaded me.
I hope I'll be happy!
