Haha, I'm HORRIBLE about procrastinating things.....but I'm also a little OCD, so once I get into a routine with something, I'm generally pretty religious about it as it...well, bothers me when I'm not.

A tad bit redundant sounding, I know, but its kinda true......its hard to explain really.
Over the course of my fish keeping years, the past year and a half or so I've been a little lazy with water changes and maintenance due to various reasons, though this summer I really jumped back into the hobby full force and have since been very especially diligent with my water changes, slipping up a couple of times only because I've been having some trouble with my health and was actually physically unable to preform water changes.
I get my handy-dandy Pyhton(seriously, I'm in LOVE with this thing....a little expensive, but one of the best investments I've ever made)out three times a week; Monday, Wednesday, and Friday. 8 out of 9 tanks currently set up, ranging from about 2-10 gallons. Monday my smaller tanks get a 75% change, Wenesday everyone gets a 50-ish% change, and Friday my smaller tanks get their 100% changes.
Sounds like a lot of work, and I'm always whining to myself about it, but really its not all that much and doesn't ever take me nearly as long as I make it out in my head to. xD Lol
