Ozone users!

[guido_kp]

yeah im still alive. i used to have a filter sock with carbon in it, on the skimmers exhaust, but got lazy and took it off. the animals didnt appear any different to me. to be safe you should run carbon i suppose. i dont notice mine turning on often, mostly when i stir up the dust thats settled on the live rock - and it runs for an extended period. you can smell it a tad, then. that crisp headache inducing smell lol. the unit i have is rated for 300mg/hr but i think that is very optimistic rating. i am more worried about the CO2 bottle under the tank than the ozone.

i havent heard that ozone can cause cataracts. i know that UV radiation can and will cause them. perhaps youre confusing the depletion of the ozone layer with this? i suppose if one had a uv powered ozone generator versus a coronal discharge, they could be exposed to the uv. but unlikely. i would like to read more about ozone induced cataracts, if you have a link.

into my skimmer, no carbon

With DIY reactor or any reactor, how do you force the ozone into the water, agaitation, pressure, it just happens, etc.?.

the ozone needs to be fed to the reactor with an airpump. some units have them built in, some do not. in my case, the venturi on the skimmer draws the ozone in. it is t'ed into the skimmers airline tubing. one thing i havent seen mentioned, is the use of an airdryer. this will increase ozone production and prolong the life of cd type generators.

I'm sorry but this is too funny.

Did you finish high school?

Ozone in your tank will not cause cataracts...

You're referring to holes in the ozone layer, within the atmosphere on EARTH.

This has nothing to do with your tank, you will not get cataracts from your tanks ozone.

Does reef central have a "best threads"?

Wait, they have tank of the month...... hahaha.

HAHAHAHAHA

 

[eastonreef]

wow .. that was a little harsh.. i have heard of the tank and equipment causing all kinds of strange things ... being mean will not encourage people to ask questions if they think people will laugh at them...

-- back on to the thread -- i am using a home made dryer... if you go to a craft store you can get crystals to dry flowers. i have the airline tube from the ozone unit go into a container with the crystals in it.

Anyone have some designs, plans or even pics of a DIY ozone reactor. A simple one? I understand the concept but would like to see something visual!

 

[JustinReef]

I found some people using a VERY simple method...Just basically a long length of flex PVC that the ozone is injected into along with water of course and they mix slowly through the entire tubing. Apparently its working pretty well. Anyone here done this?

 

[erbio]

Just make sure y'all use a controller to monitor ORP.

Here are some photos of one that I built for a friend of mine:

Basically water enters through the barb on the left and ozone enters through the attached hose. The water flows down over the bio-balls (this increases the surface area and time on contact with the ozone) and then exits through the second barb from the bottom of the reactor. Some side notes: the tubing and barbs shown are not ozone safe, that is they will fail over a short amount of time. I called U.S. Plastics and they were able to point me towards some ozone safe fittings, I just don't have any photos of those. Since this is a closed system the pressure forces the water out along with air/ozone. So we changed the exit so that it flows through a 2" pipe full of carbon. I'm sure if you put a relief valve somewhere halfway down the reactor body you could eliminate bubbles, but this works pretty good. Lastly this whole thing can be built with PVC tubing, you just wouldn't be able to see inside. Hope this helps!

 

[eastonreef]

very nice work... is there a reason you would not want to inject it into the skimmer?

 

[JustinReef]

It degrades the skimmer over time making the acrylic thinner and thinner until it cracks. It may take a long time but I have a pretty expensive skimmer and do not want to risk it. There are other reason like a short contact time too but thats the main one for me anyways.

I don't want to restrict airflow at the venturi, I would rather use a seperate reactor.

lvpd-Very nice, I may build one similiar, but square (cheaper).

 

[spreston]

I will be using my AC III for control. What do you typically turn off when ORP levels are satisfied, air, generator, feed pump, etc? I assume the generator itself, as not to backfeed water up the airline.

Do you have plans? I am still looking for something really simple I can build.

 

[eastonreef]

cant you modify a phosban reactor http://www.toofishy.com/product.php?productid=80231&cat=481&page=1 and run it into this? you can fill it with carbon ........ would this work? if not why?

 

[snorvich]

The problem is that most reactors are not made ozone safe and will be damaged in the longer run. That is not a desirable thing for a skimmer or other item that is valuable. If you have a throw away skimmer, perhaps. MTC and others make ozone safe reactors. Always run with a controller; set point should be around 375-400. Check your ORP calibration on the controller periodically.

Always use carbon on the outputs (water and air). Be sure those reactors are also ozone safe.

You dont see alot of ozone reactors especially the bioball design in use because they do not work very well at all. One of the easiest ways to inject ozone besides the skimmer of course, is just a roll of tubing. Throw bigger pump like a mag 18 in your sump, push the water through a venturi then through 25 ft of 1/2 or 3/4 tube. The o3 connects to the venturi. Run the output to carbon.

Ok, yeah this is what I was asking about earlier. What kind of tubing can you use that is safe for ozone? Or would you just use flex pvc or something and replace it once in a while? If you do it this way, is there any ozone getting into the air at all? Seems like there would not be.

 

[Donw]

I dont know the exact article but one of the reefkeeing article Randy shows how to do this and what to use. Also explains why and how it works.

He used HPDE tubing. Seems like a nice easy way to go actually.
