AquaNotes is free-ware aquarium notebook for Palm computers. This product is primarily aimed at freshwater aquarium users and allows for the logging of pertinent data relating to routine aquarium maintenance. I wrote this program to replace the paper notebook I kept to remind me when I last changed my filter media, when I got new fish and stuff like that. Note: If the link to the .zip file does not work, right click on it and choose 'Save Target As...'. This works with Internet Explorer.. I'm not sure about other browsers.
