I have a cabinet of fish supplies. Old filter, a bag or two of old gravel that I'm hesitant to throw away, some food (just treats, like shrimp and bloodworms) test kit and the bucket and vac I use for water changes. Peeeyew!
But, really vacuum the gravel and up your changes to 2 50% changes a week. That's what you should be doing anyway, unless your tank is cycled. Which, I have a feeling it isn't.
