low ORP...

[Ian]

I just got a 50 mg ozonizer with an ORP monitor for my 80 gal. The monitor reads 88. My tank is mostly SPS and all display new growth. Everything is doing great.

Could this reading be correct?? Ive read desired ORP is 350 give or take. Should I be concerned about the ORP level in my tank?? I assume I need to raise it slowly??

Can anyone give me some direction??

Thanks in advance!!
