Anyone using an ozoniser?

[andrew.flavell]

Hi
Thinking of putting one on my system.Read plenty of fores none against anyone open my eyes further?
Cheers.

I stopped using Ozone years ago...it just seemed to be another thing to mess with and calibrate and run through carbon....

Not that it's a bad thing...I just don't see it necessary.

Ozone is in my opinion (and almost every public aquarium in the world) one of the best tools for improving water clarity and skimmate production. I use ozone at the facility I run with about 15,000 gallons of saltwater aquariums, and it keeps the water so very clear it is amazing. The controlers nowadays are so much easier than the ones used years ago when ozone first came onto the scene. Some of the hobby units (red sea) come with a precalibrated probe, every year you replace it. I would never run a marine aquarium (reef or fish only) without ozone. You can run your ozone safely around the 300 ORP range without much worry or you can run it 350-400 with more need for precision. The higher ranges do tend to help with algae inhibition if you are having problems with it, while around 250-325 you will just see clear water with improved skimmate. That's my five cents

Yes I'm using ozone. Believe me, I thought my water was clear, but I was wrong after using ozone for sometimes. Yet I got more skimate out of my G2 skimmer too. I'm keeping my level around 350. Just watch out when you start using ozone. I got one SPS bleached out 'cuz it suddently got more light. I'm using the cheap Milwakee Controller and Enaly ozonier.

I do not believe in running ozone as it's another thing to have to test, plumb etc. My water is crystal clear and my ORP sits about 413 all the time, I just don't see the need?

What are you testing your ORP with? Sounds like it needs to be recalibrated if you are getting and ORP of 413 all the time. There is no way that could happen. A constant ORP reading is almost impossible even if you are trying to control it with ozone.

Yet I got more skimate out of my G2 skimmer too.

Did you inject it into the airline going into the pump? I've tried that and had problems with the bubble production in the skimmer column. Almost as if it was overwhelming the needlewheel.... Any ideas?

 

[superedge88]

What kind of bubbles were you getting?

 

[Seasapience]

Bigger than normal. I tried a luft pump to feed the ozonizer so I could dial down the air production but it didn't work that well.

I've been running ozone for a few months now and love it. The water cleared up from yellow to amazingly clear. Since that time I've noticed that my corals seem happier with greater polyp extention that may result from the break down of toxins within the water or better light penetrance. Ozone is a great tool if run correctly and monitored with an ORP meter.

Alot of people buy the enaly unit from china, which is what I have. The airpump model produces alot of ozone in a relatively short time. You need to either get the enaly unit without the airpump or get a smaller ozonater.

Downside is the ORP probe needs some soaking in vinegar every 1-2wks to keep the probe accurate due to buildup on the metal prongs. Also, when installing the ORP meter raise the ORP slowly b/c you can easily bleach your corals.

I run my ORP at about 400 where there actually seems to be less skimate coming off my skimmer than when it runs closer to 300. The skimmate that is removed has gone from a foul smell to pure rank. It now comes out as a brown odiferous sludge.

I've used it on a crowded SPS tank for 14 months and it works well IME. I thought my water was clear until the O3 kicked in -it is really amazing to see. I run a red Sea 100mg controller unit at 70mg without the dryer beads.

 

[JamesJR]

I don't think I will use it again in the future because of careful consideration into how it works. Ozone works by cleaving double or triple bonds in organic compounds.
In doing this Ozonolysis produces ketones, aldehydes and carboxylic acids. These compounds dissolve in water much better than the hydrocarbon ones did and are thus harder to remove using skimmers and activated carbon. The products are still in the water and can be used as food sources for bacteria.
Knowing this I am just going to invest in a more powerful skimmer in the future instead of messing around with ozone again.

 

[superedge88]

So feeding bacteria is a bad thing? I don't follow your reasoning.

 

[JamesJR]

I am just saying that the byproducts from ozonolysis can work as food for bacteria. I am not saying this is a bad thing. What I am saying is that I would rather have these compounds removed by a skimmer than have them broken down into compounds that could be used by bacteria.
Ozone does clear up the water and it does a fantastic job at this but it does not really get rid of many chemicals. In the case of organic compounds it just breaks them down into smaller compounds that don't really absorb or re-emit EMR, so that is why it gets rid of the yellowing.

 

[Mache62]

which enaly unit do most people buy?

 

[GROSSR]

How do you get rid of the Ozone smell?

[JamesJR]

You should not be having any sort of ozone smell. This can be a serious threat to your health. You should pass the water that is coming out of the skimmer or chamber through activated carbon.
Also the air that leaves the top of the skimmer should also be run through activated carbon.

 

[andrew.flavell]

Try turning down the ozone.

 

[Paul B]

Without going into too much details I will say that I am using 50mg/hr of ozone on my 100 gallon reef with no controller or carbon since about 1979 or so. I have never tested ORP as I can tell by the health of the animals. I use such a small amount of ozone that I am quite sure none of it reaches my tank. I would always use ozone as a tool as I use a skimmer as a tool. You can live with out them but they help. I have had fish live over 18 years and many corals are over ten. How bad could it be.

Im running around thirty mg for the last 3 or 4 months and the corals have gone mad. Full extension and opened right up. Definately improved my system.
Massive reduction in skim though. Proves it must work to me.
