Favorite and least favorite chores?

[reefgirl189]

Concerning your general aquarium maintenace:

What is your least favorite maintenance task?

And the one you like to do the most?

I'll go first:

I hate mixing up the dosing recipes. It's messy and I haven't found a very efficient way of doing it yet. I also suck at dosing in general and I'm having a hard time finding the right levels for my tank.

My favorite would probably be cleaning the skimmer. I know you're all thinking I'm crazy right now, but it is! I can see the results of my hard work right after it's done and the smell doesn't really bother me after changing diapers for two years.
