New product contest! First person to guess what the new scrubber will be (or more likely, who is closest) wins a $100 model HOG.5 scrubber:
https://www.santa-monica.cc/product.asp?itemid=21
...which can be used for filtering a small tank, or growing live food for a bigger tank.
o Can be shipped to any winner in any country.
o Only one guess per person, unless I restart the guessing.
o New people can guess until I think one is close enough.
o Someone will definitely win, even if not very close.
o Hints will be given periodically.
o You can share this contest on any other site you want, but I'll need to see the guesses for them to count.
o Contest will go at least a couple of weeks.
o Enter your guess by just posting a comment.
The first hint is that this model is not a simple mod (like an extra LED, etc) of the current models; it looks nothing like the current models. Also, it's still in development, and will not be available until next year. All guesses from all sites will be posted here so you can see them.
Hope you win!
