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?

Did you atemp to calibrate it?

They claim it’s factory callabrated ready to use

EC is presumably conductivity, which is a different units of measure for salinity. 35 ppt seawater has conductivity of 53 mS/cm.

 

[scotty333]

Oh right , cheers boss I’ll have a check now

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

Ozone generator on route

What multi tester did you buy?

 

[scotty333]

Ozone just arrived as you asked

Question…

This states 1000mg/h so how long should I run it ? Like 15m per day to start?

 

[scotty333]

Decides on 4 x 30minutes

Are you running it through your skimmer or a reactor?

 

[scotty333]

Into the water in tanks on the skimmer because it slows the air on the air inlet
