Eshopps NANO Overflow Box, 30 gal tank.

The new Eshopps Nano Overflow Box is a perfect fit for smaller applications. Many hobbyists have smaller tanks they don’t wish to drill, but still want to benefit from the use of a sump. The Eshopps Nano Overflow Box is relatively low profile, measuring 4×2 1/2″, while handling up to 200 GPH.
