ORP

[Rollman]

Hey All-
I think Im finally on the backside of my diatoms post cycle. My ORP has been climbing from 320ish to 420ish during this time. Any correlation between algae dying and rising ORP. From what I’ve read, I’m not sure why Neptune has a probe for it. Thanks

I plan on getting an ORP but mostly just because I run Ozone, and I like toys

ORP can be useful for ozone or running a sulfur denitrator; otherwise useless. You can repurpose it for a second pH.
