Change in average ORP after Blue Clove Armageddon?

[acroholic]

Guys,
I recently eliminated about 4 square feet of blue clove polyps that had been infesting my 300 gallon SPS tank for the last two years. A veritable plague, growing on all bare rock that received light. I am about 2-3 weeks post elimination. Got some cyano, but this was a huge amount of biomass to kill off at once, so I have been doing higher than normal water changes, skimming wet, and rinsing filter socks daily.

Anyways, I noticed after things calmed down that my ORP has jumped an average of about 100mV, and is stable at about 370, up from 270 or so. I use a very low dose of ozone in my skimmer just for water clarity, and that has remained constant throughout the entire process.

Huge amount of living biomass was removed from the tank, probably 50% of the total, if you compare the amount of blue clove tissue to the acros/zoas in the tank. Fish population is the same.

Can someone explain why the average ORP has jumped related to the removal of the blue clove polyps from the system?

Seems like an Ichthyoid or Grouper Therapy or LilRobb question, but anyone who can explain this feel free to post.

Before I can answer you have to tell me what ORP is. . OK even after you tell me I won't answer but I will pay attention and learn.

ORP stands for Oxidation Reduction Potential, and instead of me giving some half arsed explanation, here is a great article on it by The Man, Randy Holmes Farley.

Maybe more frequent water changes are replenishing oxidizers.

Or you may have deplinished potential reducers by removing the cloves?

Huh?:wow2:

New theory: the clove polyps have very little to do with the increase in ORP.

Here's what I am thinking. Organic waste is a reducer. In result of wet skimming, and increased water changes, you are more efficiently exporting organic waste. It takes a lot longer for matter to oxidize than it does to remove it manually.

The ozone that you are adding is keeping the number stable. Less reducers means more aavailable oxidizers for the probe to detect.


Just a theory.
