You can see some light through Rubbermaid Roughneck tubs. Does this cause problems? Read about a rubberized black spray paint but don't know the name of it now that sticks to plastic. Do you need it to prevent algea??

Hey, I use a black spraypaint i picked up from my local ace hardware, its just called "Plastik". Check your local hardware store, you should be able to find a spraypaint meant for plastic.

hey dude if its not lightproof algea will build up and clog airstnes if your doin dwc and your roots need darkness
