will this work? Siphoning from tank to tank

[abcha0s]

I can't see a problem with the logic - someone else might?

I would point out the obvious. You really should upgrade the sump pump and split the return between the two tanks. If you really can't afford it, maybe wait a bit before bringing the tank online. Telling your wife you are delaying the project so that you can be be financially responsible with the new tank will be a great way to win over her enthusiasm.

Hope that doesn't come across in a bad way - I get pretty wrapped up (read obsessed) in my tank projects. Sometimes it helps for someone to tell me what I already know.
