Hello, my name is K.C. I have been keeping various aquiums and inhabatnts for a while now. I recently started my first mixed reef tank; it is only a small nano to get things going. I am learing so much so fast and this group has been great reading all of your insights and experice. I have been doing my testing regular and keeping track via a basic excel spreadsheet, but it is just not as clean and organized as I would like. I was wondering if there are any good applications for iPhone that anyone has used with success and really likes for entering and trending their tank parameters data.
