Many have attributed stray voltage in the aquarium to many common fish diseases such as lateral line and hole-in-the-head disease. Stray voltage comes from heaters, powerheads, pumps and other sources. This can now be completely eliminated by installing a `ultra ground` probe in each and every aquarium. The `ultra ground` probe is made from a solid titanium rod that utilizes an insulated transition joint to insure corrosion protection and leaching of metals into the aquarium. Don't take a chance on having stray voltage in the aquarium, install an `ultra ground` today!
