I do <raises and waves hand>. Well, I did anyway. Haven't for quite awhile, 'cause my fish were at someone else's place for awhile, then a lot of them died, and then I moved again, and I didn't have my computer set up and, well, you know... I just got my tank "settled" at my new place now, and haven't started keeping records again. I probably should, however.
When I was keeping records, I simply did it using Excel (spreadsheet program). Each tank had its own "worksheet" in the file. On the top of the spreadsheet, I typed in what tank it was. Then, in the first column, I put down the date. I then made columns for each water test I had (gH, kH, Ammonia, Nitrite, Nitrate, etc.), then I think I had a column for notes, one for meds, % water change done, and I forget what else. The file's not on this computer, so I can't check and see. Then I simply filled in the date and anything that "happened" on that day. Of course, I didn't run every test every day, nor did I make notes every day, unless the tank was getting treatment or its residents got moved around. I made notes when I added plants, added or removed fish, if fry were born, if a fish died, etc. It worked quite well and after the initial time it took to put it together, it was fairly quick. Once I have my computer up and running, I can e-mail people the file if they want to see it.
That answer your question sufficienty?
