Is this a saltwater tank? I'm I reading it right that you did a 100% water change in October?
Yeah, I log everything I measure because, well, just because, I guess.
The tank is freshwater and yes, in early October I swapped out the generic substrate for Seachem Flourite, so I marked that as a 100% water change.
I'm no Excel expert, but I have figured out how to do some interesting things with the chart. The most useful is that it's dynamic so I can choose to show all the data or just a time-frame I want. Normally, I only look at the last 30 days just to see any trends. Most recently, I've been experimenting with PPS Pro fertilizer which is why the Nitrate and Phosphate levels are not yet steady.
If you want, I'd be happy to send it to you in .xls format so you can play with it.
