Orp?

[cpagego]

I was doing some reading this weekend about ozonizers and monitoring ORP. I plan on having a tank with a very heavy bioload and thought that monitoring ORP would be a good thing. Does anyone out there monitor ORP and practically speaking, how useful is it?

Without running ozone, not very. You get an idea of how much crap is in your water, but I could get the same idea by looking at the sludge coming out of my skimmer at that moment. Some guys do it, but if your husbandry is fair, its not really worthwile in my opinion.
