Hi,

I am debating to get the ORP or the salinity module. I am wondering which one is more useful to have when away?

If salinity module, then it can be useful if the salinity drop due to the leak or skimmer overflowing etc...

what about the ORP, does it have any useful indication when someone is away and monitoring the tank for possible catastrophe? What type of indication can it give to indicate a problem?

If your not running ozone orp is uneeded. If you are running ozone. I would get the orp

so ORP does not give any useful indication if a tank crash?

Yes and no. ORP is oxidation reduction potential. A higher number is said to be higher. But nobody know what it actually suppose to be.

Means there is more oxygen in the water?
