Good brush for scrubbing rock

[ReefsandGeeks]

I'm looking for a good brush that I can use to thoroughly scrubb off my live rock in my tank of any algea. I use a toothbrush, which works just okay, and is pretty small for use in a 150 gallon tank. Any suggestions?

I have no clean up crew other than a pair of urchins. I have a porcupine puffer, and a mixed reef. I'm sure the puffer would eat any snails or crabs I'd pt in the tank.

Also, any suggestions for more clean up crew that are both coral safe and puffer safe?

Go to your local big box hardware store to the cleaning products isle and pick up a couple different all plastic stiff brushes. I have several of different sizes. The wife knows (now, at least) to never use them for anything else!!!
