There's a video on the kickstarter taken 2 days ago, talking about biofouling and such. It's only part 1 as well.
Main points:
Disk is always moving to stop snails from taking rides and always wiping optical sensors.
Fluorescent disk may last longer than a month, but 1 month was what they felt comfortable with saying, you'll have to experiment.
Each optical sensor has 4 LEDs measuring from different angles, and if they don't add up right it'll let you know something is up.
Disk and sensors are cleanable. Nothing abrasive though, DI or just saltwater and a sponge or your finger.
Alkalinity calculation is based off of oceanography calculations, which are very accurate in normal seawater. If you're making homebrew salt with extra borate it might throw it off.
I think that was about it.
