CO2 in house increase, im aware of. what about the hand that holds the cig? i smoke, and just thought of this. how much nicotine residue is on my fingers when i rinse them and then place them in the tank/sump? how would it effect the chemistry? i noticed during cleaning today, my fingers had a stronger aroma of smoke after i had them in the tank. just courious. thanx & REEF-ON!
