hey i was wondering as to where you plugged the aligator clip into the charger?
i have a cellphone charger that is 500ma and im wondering if i can use this.
will this harm my other tank mates? my fish arent going to start swimming upside down RIGHT!
and what is the purpose of the carbon from the pencil?
and what was the purpose of the shrink wrap?
i think i want to try this i just was curious about these few things.
thanks in advance. jeff
