There's an inspiring video on this subject:

"Internet of food: Arduino-based, urban aquaponics in Oakland"

The fish will be producing lots of N anyway which isn't going to be good for the flowering stage.

Alice blagged a seneye http://www.seneye.com/ which does the measurement using replaceable slides and a camera. I almost managed to break open the SSL connection that seneye uses to send its data back to their servers, enough to see the XML data they were sending, but was stymied by some unknown handshake that must happen when the thing starts up, when deployed I couldn't see the data :( Got bored with it after that, messing around with an app in Windows when I'd got involved to do an arduino project :-P
