Blacked out HDPE container ideas

[rayadog]

I have just emptied the above container. I feel like I could do something with it but I’m not sure what; besides storage. As I began to write this I guess I could make a light shade for my reef flare. Or nano/pico ATO container. I don’t have a doser yet so unfortunately can’t go that obvious route.

An ATO container is never a bad option!
