Orp

[Scotty333!!!]

Hi guys,
Now I know there’s not much interest in ORP but I got a multi tester today , ph , orp, ec, salinity , temp

Orp was 84
Ph 8.3
Temp 25.5
Salinity 1.026

I don’t know what ec is for

Is that a normal reading for home reefs?

Calibrated the tester and it’s 190 when it should be 256 so it’s 66 low
Tank is 116 so Orp will be 182

In over 40 years in the hobby, I've never tested or paid attention to ORP. So, I won't be much help here

No I’m not interested in raising it but the multi tester has it so I wondered what it was
Lfs was 260

pH (acidity and alkalinity), EC (electrical conductivity), TDS (total dissolved solids), salinity, S.G (specific gravity), ORP (oxidation-reduction potential) and temperature.
ORP can vary a lot. It is more useful to watch how it's trending than what the actual value is. If you stir up dirt in your tank it can go down 100 points. If your sulfur reactor goes wonky it can go from 400 to -49.
I use ozone and use orp to regulate how much is dosed.
Well maintained mature tanks trend to 400. Average tanks probably run between 130-300.
What does it mean? That's complicated.
