tlhood's first tank - 34g RSM 130D

[tlhood]

The collection cup is fine, it fits into the back just perfectly, and I like that the lid flips over and clips into the bottom so that no crud drips out as you move it to the sink.

The cup isn't a snug fit, but it sits fine in the top. As long as I keep an eye on it to make sure my water level doesn't rise above it, the cup not "clipping in" isn't an issue for me.
