Well since your gauge is meant for cigars and not pets, it doesn't fit with what we use for our crabs. The warranty and recommendation you posted doesn't apply to the thread. In your original post you should've explained what brand you used and that would've saved the thread from getting off topic.

So as I stated before, the salt method works on the gauges we use for the crabs tanks. Should you use the gauge for cigars then skip this topic.
