We never discussed the effects stray electrical currents have and the long term effects as it relates to the immune system and low level stress. Even with the slightest electrical current present the comosition of the water will increase conductivity the farther we move from total DI pure water to seawater. Tempure als has an effect on conductivity. This is just somthing I was thinking about the other day. Also as I mentioned in an earlier post the inclusion of vitamin C will help boost the immune system as the fish ages. Just some things to think about and discuess among the cicliaphiles.
