Wow fantastic, thank you. That is exactly what I was looking for... Are you aware of any other DIY arduino reef projects? Have you purchased any components yet?

Here's a pdf file to the most recent build http://code.google.com/p/jarduino-aq...a.pdf&can=2&q=

Here is the thread on the above pdf manual and the youtube video. http://ukreefs.com/index.php?topic=117.0

Here is a guy who sells Arduino shields assembled or kit form. http://www.practicalmaker.com/ He has shields for pH, ORP, salinity, extra PWM channels and a full controller. He is in Australia. I am thinking of getting a bare PCB for the pH and ORP sensors because they are easy to build and only $11.25.

I haven't built my cat4101 drivers yet (or the LED's for the 90 gallon for that matter) so this power shield is very enticing. http://www.chestersgarage.com/produc...r-led-shieldIt is a shield with the LED drivers integrated - 4 channels. For my needs, I will need 2 of the $39.95 versions.

The one thing I may order immediately is the version of the megashield with the built in clock. http://imall.iteadstudio.com/prototy...120717001.html They were out of stock yesterday, but have them again today for only $5.50. All the other parts seem to be readily available. This is the one that sells out quickly.

If I get everything done the way I want it, I should have a controller with way more features than a Proiflux III ex for well under a hundred dollars.

Let me know if you want links to the cheapest touchscreen and Arduinos I have found on ebay.
