Ozone generator

[WVNed]

Full disclosure. This is how I do it It has been running many months.

You have to design a system that is safe and works for your system. Yes I gassed myself a couple of times at first.
I tried 3 smaller generators and they ran themselves to death so I have a much bigger one now.
My system is 400 gallons total.
Someone PMed me about running ozone and this was my answer.
I only push my ORP up 30-50 points.

I do it my own way. Not sure this will help you much.
I have an air pump I modified to have an in port I could attach to outside air. I use a BRS air desiccator. I pump the dry air through an Enaly 800mg/hr ozone generator and into an LifeReef SVS-36 skimmer.
That skimmer uses air recirculation so it pulls air from the collection cup for a venturi. I inject the ozone into this line. The top of the skimmer has a vent hole. There is a bit of positive pressure in the collection cup from the Ozone air pump. I put a tube from the vent hole back to a second PVC tube that also goes outside.

That second air tube feeds outside air to a SRO-5000 needle wheel skimmer. So the second skimmer ingests the excess ozone that comes out the top of the first skimmer.

A Milwaukee ORP controller runs the ozone generator.

it all looks like this

1 outside air to dryer
2 air pump
3 ozone generator on a shelf I made
4 tee into Lifereef skimmer air line
5 unused ozone vented back to 2nd outside air manifold
6 2nd outside air manifold also attached to SRO-5000

This pic was while I still had the Aqua UV 80 watt in the system.
A skimmer with significant ozone in it doesn't skim. A little stuff comes out but not much. That is why I have 2 in my system. I learned that from the guy that makes the lifereef skimmers.

There is no carbon to catch ozone. I have the ORP controller probe in the output of the LifeReef skimmer and use that value to run the generator. The number displayed on the controller is either the reactor output water value or settles to the water in the system value if you turn off the generator.

I have been using this for many months. If you get any smell it is outside coming out of the second air manifold. I do not try to drive my ORP any higher than 360 in the actual tank system water.

There you go
clear as mud.

Any skimmer can be used with ozone?

In general with low doses yes. Ozone O3 is an oxidizer and may affect some plastics and airlines reducing their life. My Tunze DOC skimmer comes with a dedicated ozone port and filter bag for carbon on the waste pipe, that was one reason for selecting it as it took the guesswork out. Ozone safe airline is readily available.

I guess it depends why you want to use one. I never thought they were a necessary piece of equipment, unless you have a massive aquarium (like hundreds of thousands to millions of gallons) and need it to keep dissolved oxygen levels up. The same clarity can be achieved with some GAC use, and parasites can be controlled with QT procedures and UV sterilization if desired. I worked with them on very large/heavily stocked systems in the past, but personally have never considered using one on a home aquarium.

So all I have to do is run carbon, UV and set up another system for QT.
and carbon causes HLLE maybe.

Instead of running Ozone.

Nope - I use an oxydator. an equipment that´s do nearly the same as an ozon generator but is driven by hydrogen peroxide instead.

In my former aquarium I use a ozone generator and I had a lot of help of it.

Sincerely Lasse

Same here. Have been using one for about a year and a half. Super low tech, no wires, no power, easy.

Nope. You can choose to run your system how you prefer, as I've said many times, it's the beauty of the hobby. As I prefaced, that was my personal reasoning why I wouldn't run ozone on a home aquarium.

 

[Lasse]

I only push my ORP up 30-50 points.

This is a very important statement. There have been a lot of people running around 250 in orp naturally - and directly tune in to 360 - 400 in ORP when they start with an ozone generator. This sometimes stress the inhabitants and in some occasion it has killed fish and invertebrates, Start with your natural ORP value + 30-50 points. Wait for some weeks and rise more if you need - but always in small steps. If you run in 360 natural - it is no problem to dial in 390 - IMO

By the way - You have a very well thought out system @WVNed - I love the way you think

Sincerely Lasse

What are the advantages and disadvantages of using ozone in today’s reefing ?

 

[Jessesun]

if you want to make ozone generator work well, you must know details about ozone, ozone generator, like CO3, contact time, etc. We are a ozone machine factory from China and my email [email protected]. any question about ozone and ozone generator, please reach me for answer

I used Ozone 24/7 full blast with no carbon on my reef for about 35 or 40 years with no problems. My generator croaked 4 years ago but I want to get another one.

I don't like carbon for a few reasons and will never use it. Besides HLLE which is "assumed" to be a main cause of that condition I just feel it is un natural and removes as many good things as bad.

I also have a 5' DIY Ozone, tsunami and earthquake proof skimmer.

Careful Paul
If I ran the ozone generator I have now "full blast" it would not be good. There are all different size generators

WVNed, you can gauge the strength by seeing how fast the paint peels off your ceiling.

It will do it. Except the ceiling in the fish room is just floor joists and wiring.
Most Aquarium generators make 200mg/hr of less. I got a lab generator that does 800 on dry air.

Thats how they invented "Glo Fish".

I read all those.

A question. Does Ozone do basically the same thing as Hydrogen Peroxide in an aquarium.

A simple answer will do. It is still early and not all the coffee is in me.

I turned it off last night. I am wondering how and if I will use it again. I have used it 2 ways. Low dose continuous delivery and high intermittent dose with the controller.
Both produce the ORP of around 350 I was looking for.
With it off I read 267 this morning.

It does some similar things, but not some others.

You can stop here until after coffee.

Hydrogen peroxide may reduce Cu++ to Cu+, which might be why ORP sometimes drops when adding peroxide. I do not think there is such a possibility when using ozone. That might actually make copper more toxic in reefs, if it happens, and if enough is present.

I think I am going to put it on a smart outlet an run it low dose intermittently. I went hog wild with all the things you can do and now I am to the the less is more stage.
I think all I want it to do is decolorize the water. It should do that running 1 or 2 hours a day at 35% output I think.

That may be more than adequate. Even once a week may suffice.

I will start at 8-9pm every other day and cut it back from there.
