Does anyone keep a log or journal of activities involving their tanks? For example, water chemistry readings, when a tank is set-up, new fish purchases, notes on breeding, etc.? I'd like to just use a tablet or looseleaf binder to record things rather than creating some kind of a spreadsheet or whatever. I'd be especially interested if anyone has some samples they'd be willing to share. I've tried looking on the internet for some software, but haven't been able to find anything. Thanks.
