My tank's ORP is typically over 400.
A few weeks ago I noticed it was in the mid 300s.
This morning it was down around 300.
Today post water change it is about 290.
I need help determining the possible cause.
ORP Probe on Aqua Controller gone bad?
Tank trying to crash?
?????
The 150g tank has been established for just over a year.
Last week I did a 40 gallon water change w/Red Sea salt.
Today I did a 25 gallon water change mix of IO and RC.
Alk 180 ppm
Calc 400 ppm
Mag 1350 ppm
Temp 78
pH 78.5
Nitrates 0
Phosphate 0
Salinity 1.026
Thoughts, suggestions?
