Does salt have an impact on Beneficial bacteria?

Especially in small tanks?

No not at all. Maybe if you were to pour salt in your filter it could do some damage. But the amount you would use to treat the tank will do nothing to it.

agree with the above post..
it won't harm good bacteria, and is a must have for your tank..
