Ozone

[Proteus]

Peroxide and pomagrante are the next best oxidizer a to use but still must be monitored.
The nice part about peroxide is once it oxidizes otganics it becomes water.
Uv is another way to control orp as o2 is transformed to o3 when in contact with uv


IMO there's more important things to monitor as even the reefs in open ocean Cary's so much based on things from lightning to thermal vents.
Even the scientist who study the reefs have stopped checking and monitiring orp because it has such a large swing number
