Reading the DIY divider post... try finding a mesh that's plastic, and without a "rare" color would be great, the color could dye out. And, well... if you do a 100% water change, and your tank is cycled you will get rid of all the bacteria. But, it's not that big of a deal... you can always recycle it. In a 2.5 gal tank it's not that complicated, many say that such a tank can't even be cycled. Or, try just pouring 75-80% of the water and put the divider back in, then refill.
