Redox???

When my lights are off the redox levels are higher but this is related to temp drop when the lights are off. When you change your water the redox levels are low anyway. Also the drop in redox is related to where you have the probe located and it does take a while for the redox probe to re equlibrate after a water change( a couple of hours.

I have one in my tank also. My experience is EXACTLY the same as fencer, above. I've tried aerating my water change SW...no matter what, that new SW causes a temporary reduction in measured ORP.

Well mine read from 220-280 before it met its untimely demise. I know you know this but figured I should reply so there is reference to this for others.

So you had higher REDOX readings for some time...then a shift down to 220-280...then...demise?

The lower/change in REDOX was an indication that something was wrong?

No her Profilux met its demise. She had a flood and lost the profilux.

The way i understand it the lower the number the cleaner the water what i am trying to find out is what is the highest reading you can sustain before something bad happens.

I have found sites that say 350 is bad and others that say 450 is good so i am lost.

That's why i would like to know what others have for readings mine used to hang around 350 360 and now seams to climb to 390 400.

So anyone who has one readings would be appreciated.

I think you have that backwards..I think the higher the number, the generally "cleaner" the water. You can use REDOX to control ozone. When the REDOX goes down, you add ozone.

1. Clean your probe
2. Any higher than 400 is too much...esp if you are dosing with ozone
3. I have a lot of sps growing in the 320 - 350 range
