Serious dangers of salt water tanks and any tank

[Aquattro]

There are several posts over the years about the dangers of gear and critters in salt tanks. This is due mainly to faulty equipment, although sometimes it's hard to know it's faulty. I got an old Hagen 402 from somewhere, plugged it in and it spun, so I added it to a mixing tank. Plugged it in. Put hand in water and jumped about 5 feet up Cracked wire on the cord. Always check new stuff, and routinely check current gear. Keep it clean, remove salt build up, and buy life insurance
