A post so nice, you posted it twice! ; ) Actually, just the very smallest bit of tape is contacting the water. I wrapped the length of the tube (Starting at the break which is just under the surface) and its working well. I don't want to leave it that way. There is shrink tubing that I've used in electronic repairs in the past. You basically slip it over the wires (plastic tube in my case) and then apply heat from a lighter or butane source. The heat tubing shrinks tight around the wires. Im sure this would work, however, the diameter of this is much larger than your average wire, so I supposed I could check Lowes/Depot. Suffice to say I think I may just pick up a new HOB
filter. This one is a little underrated for my tank any who.
The plastic tube probably wouldn't work as it has to air tight. If even a little air gets in, it causes the filter to spit and stutter. Sounds like a car in dire need of a tune up.
