ideal orp

[Gustavofos]

Qual é o orp ideal para aquários com corais moles e lps? Eu deixei o orp em 450, é muito alto?

ADMIN TRANSLATION:
What is the ideal orp for aquariums with soft corals and lps? I left the orp at 450, is it too high?

There is no ideal ORP, or at least no data to suggest which range is best for which organisms.

Are you using ozone or other oxidizers? If so, do not drive the ORP any higher than 450 mv. If the ORP is naturally 250-450 mv, those are all fine.

use ozone and I'm keeping it at 450 with a controller

Is it too high? I only have soft corals and lps, in addition to fish.

I discuss ozone use here:

I would lower it a bit myself, maybe to 400 mv.
