Ozonizer

[Detri]

I have an Ozonizer which I run on a controller.

I was wondering. If I have the controller set to turn the air pump on and off as the readings raise and lower, would it hurt if the Ozonizer was set to a higher percentage?

In the manual it gives you basic rules for running it for the size of tank you have it running on. For the size I have it says to run it between 55% and 60%. Could I set it for 70% or 80% and have the controller turn it on and off as needed?

I trust this controller with my tank. I have been monitoring the controller and probe over the past few months. The readings have not been off at all. I have been calibrating with 3 different fluids each time. (by the way Pin Point Redox fluid seems the most stable) according to my records it has been dead on every time.

At the suggested setting, my Redox/ORP jumps from 280-380mv on a regular basis. If I turn it up 10% it stays stable at 370mv-380mv. I'd like to get it to stay between 390mv and 400mv if I could.

Hi do you have a ozone reactor,and do you use a air dryer? If so you can get away with turning it up some. sea water run's from 350-400 in some parts.

 

[DonW]

Just turn it up a little at a time. Just keep an eye on your orp and keep the cabon fairly fresh. Your concern is the bromide so again just keep the carbon fresh.

Thanks! I have been running the Ozonizer for about a month now. Yes I have an air dryer with it and I run carbon on my skimmer outlet. I'll let you all know how things are going in about a week then

 

[Boomer]

Rnning it that way should be Ok, just keep and eeee on things for awhile

Yikes! No... you cannot dose ozone by metering the air. The ozonizer will continue to produce ozone of course... or have you misphrased the question here? If not, then you can/will overdose your aquarium with unmetered ozone in excess (when the air pump is off as directed by the controller for exceeding the high setpoint)

In the manual it gives you basic rules for running it for the size of tank you have it running on. For the size I have it says to run it between 55% and 60%. Could I set it for 70% or 80% and have the controller turn it on and off as needed?

the basic rules are a terrible and dangerous guide... I wish they did not do that because it does not speak to the varying bioloads and husbandry schedules of various aquarists. Morte importantly, it ignores the only thing that matters... conductivity readings. The only thing you need to obey my friend is the accurate readings (mv) of your meter-controller.

The ozonizer will continue to produce ozone of course

Maybe you misunderstood him Anthony. Ozone production is a function of flow rate, no flow rate no zone. If the air pump is off there is not flow. If there is no flow rate the ozone just breaks down inside the reactor. He wants to leave the ozone unit on and shut-off the air pump feeding the ozone unit when it hits its ORP set-point. Although I would rather have him not do it this way. Safety wise shutting the ozone unit off is best



it ignores the only thing that matters... conductivity readings.

What do you mean by conductivity only matters ?

ORP readings are by far the safest method.

but The only thing you need to obey my friend is the accurate readings (mv) of your meter-controller. that does not tell all either.

He is using a controller, ORP to monitor it with. So it basicaly does not mean anything in regards to where the dial is set, it will shut-off at its setpoint, i.e, 300 mv, 360mV, etc.. Although I do not like this either for saftey reasons.

 

[Anthony Calfo]

I still may be missing something... how exactly does the ozone simply "break down" inside the reactor (unstable I know... but bear with me here) without flow unless there is some kind of check valve. Particles of ozone will concentrate and diffuse in the path of delivery and I have to wonder/fear (safety indeed as you say too) that the accumulation in the lines leading out (and their fittings especially) if not the recator itself (likely quite stable) will suffer from the reactive particles of ozone. Badly in short time (months) I reckon.

It just seems like a very hokey way to dose ozone when you can/should simply use the controller to tag hi-low setpoints for ORP for the constant flow into a reactor. At worst, if you don't want to run airflow at all times into a skimmer, then simply buy/build a cheap stand-alone ozone reacter (mere dollars in DIY PVC parts).

I agree

how exactly does the ozone simply "break down" inside the reactor

Try reading this, it may be easier for you. Ozone and its instability is much greater than you give it credit for when it is setting inside a dead line with no air flow, especially with any moisture at all. You are not going to have much diffusion at all. Not only that but it is heavier than any of the gases in that line.

Much thanks for the link/input.

Nice to see you up this late

Nice to see you up this late :lD

heehee... some folks think we are exaggerating when we say we literally wake up and fall asleep behind the screens during editing/crunch time. It'sthe least pleasnt time for publishing books/mags

I liken the work to US school teaching... working double-time for half of h year.

 

[Boomer]

I know what you mean especially this week, as Randy is gone till July 8. I think everybody said lets wait till he is gone and them hammer the chem forum and rack Boom's brain.....it worked I'm dead after the last two days

 

[Detri]

Hello,

And thanks for the response. My Ozonizer is also plugged into my controller power bar. So I can turn both the Ozone producer and the air pump at the same time. Which I do, for saftey reasons.

These are the readings I have gotten over the past week. It is irritating me to no end. With an Ozonizer and controller they should be ALOT more stable than this. But I am affraid to turn up the ozonizer without consulting with someone more knowledgable then I. Thats why I came here. Hopefully you can help or know someone who can.

Sorry I should have added that I have the controller set to turn off at 400mv and turn on at 390mv.

 

[Dr. Dee]

Ok this what i feel, maybe am wrong. but your tank reads stable to me and it depend's on the probe time,am verse pm and to say that your orp reads higher at night when the system is not so busy with photosynthesis,what matters is that it dose not drop at low as 245mv thus is when the danger starts with poor water quality in the tank.




Free your mind and your wasse will follow!!

Seeing a little activity in your orp record is a good thing. I'd be concerned about the probe if your orp stayed 400 24/7 since we know thats not realy possible. You also have to take the readings with a grain of salt since hobbiest orp probes are usually inaccurate anyways. Just use the readings as a general guide to your tank only.

[Boomer]

You look Ok then. That wiil make me and Anthony more happy Give it time for it to raise. This is not just going to go where you want in a week with yoru setting. If you look at your numbers it is on a slow rise, which is what you want. You could also turn up the dial setting just a bit. Where is it set to now ? You want it tor rise to your setting over about a month time

 

[Detri]

I have had it at 55% for the past 2 months. I turned it up to 65% a month ago for about a week and it went up to 360-370. I got nervous and turned it down. I was worried I might hurt the tank. I just thought I would get a second opinion about turning it up again now that I trust my Controller.

 

[Boomer]

Turn it o 60
