Who uses ozone?

I had an eye-opening ozone experience this past weekend. I've been hearing "accounts" of "tanks fried" on ozone, but don't believe it's ever really happened.

I have a few aptaisia in my overflow. Got the bright idea to turn off the main pump and put a mist of ozone into the overflow, hoping to "fry" the aptaisia.

Let it rip for 30 minutes, 100mg/hr into a standard overflow with no water flowing in or out--

You guessed it, the aptaisia are still there and quite happy, now awaiting a meal of Joes Juice. There's still some pods in there, I might have cooked a little algae, but everybody else is quite happy. The family room smelled like a thunderstorm just went through...

I don't see how it's possible to "fry" a tank unless you get an industrial water sterilization ozonizer....

FWIW, I bubble mine into the return line from the tank which runs into a filter sock, acts like an "ozone reactor", I think my skimmer runs a bit more reliably off ozone. I run 100mg/hr 24/7, pristine water quality and great SPS colors.

I just got one new/used w/ a controller. Wondering how I know if the probe is good. Supposedly was a new probe but had salt creep in the box :hmm2: My reading (before O3) is 145.

My reading's now around 230 but fluctuating. What's a good way to tell if this probe is in good working order before I start injecting? I plan on ordering calib. solution. Any other tell-tale signs? Dying to start.
 
mike, frankly I don't pay all that much attention to the orp reading. that being said, get a calibration solution to check. If you don't keep stable readings of the calibration solution your probe is shot. Like JB, I just continually does low amounts (30-50 in my 180) and my ORP readings are sort of just this neat thing the AQII does.
 
If it's a new probe, give it at least 2 weeks before you trust anything the probe tells you. They need time to settle. My probe, when new, read about 150. At the end of two weeks the probe was in the mid to upper 300's.
 
Do those of you that run ozone think your SPS colors are better because of it?

I would think the water clarity would help all by it self, but your also lowering nutrients.

One thing to be aware of is that as the probe gets fouled, the ORP reading will rise. One way I know to clean the ORP probe when I see a steady increase in ORP that can't be explained by other causes.
 
I have a neptune controler with there lab grade probe and have to soak it in vinegar once a week if not ORP slowly rise

After cleaning I check it with ORP calibtation fluid from aquamedic and it alway read 227 in a 230 solution. I never calibratre it and it is a 2 years old probe

I now run 2 enaly 300 mg/l in a 4 foot skimmer full time in my 400 gallon SPS system the water is cristal clear like never before

note that they dont have any dryer
 
Hey everyone. I was debating wether to go ozone or not, and this thread helped me make my mind up.

Last week I added the ozone, but my skimming has gone to nothing. Since added only the very top of the skimmer has any foam and it is all clear. It use to produce like 2 cups a week, now nothing.

Any remedies for this or what should I do?

Thanks all,
Kyle
 
When I ran ozone into my skimmer, I had to set it "wetter" than without ozone. The skimmate was lighter in color, but much smellier...no idea why.

Now I run the ozone into a "tap" high on the return line, with a filter bag loosly over the output. Acts similarly, but the skimmer is easier to adjust. Best of both worlds.

Since adding mine a few days ago, I've had nothing but non-stop thick foam. My skimmer won't stop foaming. How 'bout more details.. Type of skimmer. Air dryer? How did you hook it up? Air pump?

Just read John's reply. I've always run my skimmer wet maybe that is the difference.
 
Every system is different, but I think if a skimmer is producing less skimmate of nothing at all, it is because the ozone is oxidizing all the nutrients in the water.
With time, the skimmer should start producing a little bit of skimmate.
Correct me if IÃ"šÃ‚´m wrong please.

I posted this above, but think it got overlooked?

Well I have it on a euroreef cs6-1, set on the wettest it will get. I have it plumbed straight into the venturi on the skimmer, but it seems like it is getting just as much air as usual. I am not running an air dryer do I need to be? Hopefully it is oxidizing that much nutrients, but it stills worries me a little you know, not have skimmate is scary.

I thought of plumbing it straight up through the the exit on the skimmer, with an air pump to just pump it up throught into the skimmer would that work? That way it would be impossible to hold back air flow through the venturi. Also keeping the orp at 400mv may have more of an oxidizing effect.

Scot I have noticed better color and polyp extension just in the first week I started using the ozonizer. I think it has to do with both low nutrients and the clear water.

You tee'd into the venturi line obviously right? The venturi line itself still extends higher.

Ever try adding a pvc coupling to the top of your riser tube on that Euroreef? This is not your problem but.. you can run it even wetter. Worked good for me.

An air dryer is not mandatory but is used to remove moisture in the air entering the ozonizer (for increased efficiency). All Redseas' come w/ them now. Again probably not your problem.

I noticed increased polyp extension immediately. Not sure about the colors yet but, the water looks a lot clearer so I would think it'll happen.
 
My skimmer creates enough skimmate to coat the inside column with a fairly thick coating of protein within 3 days. The skimmate is somewhat wet when it does overflow toward the end of the week.

I feel that my skimmer might be underpowered. I have a Euro-reef 8-1 on a 180 sps with 12 fish (two of them tangs). I feed four cubes of food every 2-3 days.

My questions are:

1) From what I'm describing, is my skimmer underpowered? How would I know?
2) Would an Ozone system reduce the amount of skimmate, or increase it?
3) What is the exact effect of Ozone on skimming (sorry if these questions have already been answered previously)?

Thanks!

Scot-

I noticed improved SPS colors and growth after doing several things--basically going ultra-low nutrient with overdone skimming, ozone, Starboard (no DSB) and more water movement.

Same sort of thing the Zeovit people are trying to do, except with this method there's no ongoing additional drain on the wallet.
