Why my orp is low?

[gbroadbridge]

You dont see any justification that very low ORP can signal oxygen deficiency?

Are you reading the article? Excerpt:

You are misreading the article.

Please explain as it seems pretty straight forward in that excerpt regarding oxygen, what have I missed? Always willing to learn something new and not afraid to admit when I am wrong.

We are all Randy fan boys I read and re read his articles all the time as well. I agree that there is no point in worrying about what the absolute number is (210 vs 250 vs 350 vs 400) all within a "normal range". However, I think its silly to make blanket statements like "orp doesnt matter". For example lets say that if your ORP graph is constantly fluxing between 300-350 and then all of a sudden you get an alarm that your orp has dipped to 75.

I would feel that that the ORP probe has failed before assuming anything else.

How many folks actually maintain and clean their ORP probes?

There is a lack of information on exactly how they show be cleaned and re-calibrated.

I know some folks who have been using the same calibration solution for years as they don't wish the expense of a cleaning solution and a recalibration solution - which are not cheap.

Probes should be recalibrated montly with new solutions, otherwise you are simply playing with made up numbers.

I think you are talking about the absolute value a probe reports which as randy answered is not worth worrying over.

What you are saying does not have any impact on a probes reading that drastically and suddenly swings which is indictive of a potential issue and is a valid alarm worth investigating.

I am very experienced and I am responsible for at least 10 different culture systems which i must rely on an apex to monitor from remote. I know for a fact when the ORP swings and why, and I know for a fact its a valid alarm worth investigating when it takes a dramatic swing. I also know from experience that GAC boosts ORP although admittedly someone else may need to break down the scientific reasons as to why.

I am 99% positive that a very low ORP reading can be the result of oxygen deficiency as is the case when someone turns off their return pumps or loses power to their pumps. But i was 100% positive before you started bizzarely arguing with me about it.

Like i said -- not afraid to admit if I am wrong but... it'll take some convincing

What experience do you have with ORP probe?

Yes, well I'm also pretty experienced and manage a few aquaculture facilities.
I'm not a chemist or biologist but am responsible for the design of the electronics that manage the facilities.

I don't think ORP is something of concern in a reef ecosystem, unless you are using it to control something like ozone.

You are probably right, but if a pump fails I don't need an ORP probe to tell me about it.
About a dozen alarms would have gone off before the ORP even started to move.

I honestly don't think them useful.

We can argue for ever about this, you know

I just came to the thread to help OP by providing some insight into ORP not to argue about it but i feel like you were trying to make me look stupid or something. Ive been getting that a lot lately maybe its me lol

Is there really a Chattanooga Choo Choo?

Just saw where you're from and had to ask. My mum used to sing that to me lol

 

[ReefChasers]

Yes its a real place lol a bit of a tourist attraction at this point i think you can rent a car as a hotel room -- but i havent been there in a while.

I am actually not a Chattanooga native I moved down here from Buffalo around 12 years ago.

Tennessee is a beautiful place, though!

Oh you are from DOWN UNDER! Wallabies and such!
