To avoid the beginner's happiness trap, I bought a storage box with dimensions of approximately 27*19*14.5. The Taobao product image is shown below. I bought it for around 10 yuan

A small water pump and a small heating rod help the turtle survive the winter.

The storage box is quite small, and I don't want all those filters on Taobao to take up the turtle's space, so I need to set up the filter box. To expand the bacteria-cultivation house in the future, I've left snap fasteners at the bottom of the filter box.

Considering the difficulty of printing, the frame and the filter box are printed separately. The assembly fits well and is quite tight.

The outlet is designed with a water distribution pipe, which helps the water to be evenly distributed in the filter box and make full use of the filter cotton.

By the way, to prevent the overflow caused by the clogging of the filter cotton, overflow holes are designed on the sides of the filter box and frame to avoid water flowing onto the desktop.
