Your options in the poll are extremes, so you really didn't give people much to choose from.
Perhaps in the future a poll should have some better choices like
1. It's impossible, that's a slaughter tank.
2. It might work, but will require a lot of time/effort.
3. It will work, but close monitoring of the water is necessary.
4. If the maintenance is good it will be nice.
5. It's a great tank.
If you had have given those options, I'm sure you would have seen a more accurate poll rather then
1. That's Good
2. That's Bad.
3. That's Good
4. That's Bad
Just a thought.
