Dissolved Oxygen Meter?

I've never even heard of such a thing -- but my stepdaughter needs one for a school project she's doing.

They're mucho $$$, but I have some unique friends, so I thought I'd put out an ask here... if you know what this is, and have one, might I rent it from you?

A nicer pet store that handles fish like Marine Scene might have one.

Actually, now that I think about it, every so often you find a Petco or petSmart who has a fish department person who is into fish enough that they have one at home.

You can also check with pet shops to find out if there is an aquarist society in the area. Usually someone in the fish club has one.

Awesome advice... I have a couple friends at work that are into aquariums big time (one of em has several 300+ gallon tanks in his house) so I'll check with them.

Thanks!
