Battery Vac - Super

I use this for cleaning smaller aquariums when I feel it's just not worth getting out the Python. Syphoning the gravel with this and then doing a small water change works very well. It could use a little more power, but with practice I've gotten very effective with it, and it's easier to avoid sucking up little fish than if you use the python. So, maybe it balances out a little.

Pros: Works ok

Cons: could be more powerful

I use this when I want to remove some debris from a tank but do not want to change any water at the same time. Sometimes I have done enough of a water change and do not want to shcok the fish by changing too much water. It works well but is not extremely powerful.

Pros: can use when no more water should be changed.

Cons: Not a lot of power.
