| Re: Grounding Probe I also use one... The thing you must realize is that ALL underwater electrical units (powerheads, pump, heater,Ect.) put out a trace of "stray" electrical current.. The level of which increases with the number of units you have,(Obviously). This can cause lateral line disease and other effects..none of which are beneficial to your tanks inhabitants. I've never heard of any negitive effects from using a grounding probe. (IMO) $15-$20 is a small price to pay to have a healthy system. CBR recommends using one.--->CBR |
