I'll list my tank spec, equipment and then my plan and then question some one please chime in if I'm doing this wrong and if I'm doing it right let me know that too :)

My Tank
125g tank/100g sump/40g frag tank HEAVY SPS tank with a fairly light bio load.
Skimmer (to be used with o3) ETSS 600 w/ waste collector a GAC air filter.

O3 equipment:
Red sea 200mg.hr generator
air pump
air dryer
Milwauke ORP controller

I plan to use a 3/4x1/8" 3/4" "T" to inject the o3 and the skimmers air intake. The exhaust air will flow thru GAC on the waste collector. Which I may remove and make a 2" x 6"PVC inline GAC air filter Then run the air out of the house.

My concern is running the effluent over GAC...
what is the best method for doing this without restricting the skimmers flow?

I thought about just using 4" PVC, installing mesh and putting the GAC in a filter bag. How Much GAC? and how often to change it?


Lastly does anyone know if the ETSS downdraft skimmer will hold up to O3?


I know these are a lot of question I really hope someone reads this and chimes in.
 
FWIW - Although I used the reactor, I ran the effluent (ozonated water / air mix) through a reverse flow hookup to a phosban reactor.

Have you looked at the chemistry article out on the archive that talks about Ozone. There is a nice picture or two (I believe it is jdieck's) of a modified skimmer cap to do the degassing.

How did you feed the reactor?
did you use a mj pump or something like that?

I have a precision marine large media reactor I could use fro effluent/carbon...

Right now it only have carbon and is powered by a mj1200
 
Yes - I fed the reactor from a 4 way manifold run off a Mag5. After all the manifold adjustments it was putting out just maybe 50 gph.
 
ETSS skimmer doesn't recommend using ozone. I run it with an MTC ozone reactor and it works well. You will need carbon when the water returns to the sump, and also carbon on the air intake.
 
Instead of modifying your primary skimmer. I just bought a used cheap Coralife Super Skimmer, you can hang a bag of carbon on the exhaust and tape a piece of Fluval carbon pad on the air hole on the cup. Total cost to set up this reactor was like $60. Totally easy and worth it.
 
The ETSS skimmer will be fine. If you use Vinyl tubing on the input of your venturi with ozone running through it, you will need to replace it after a year. Also, the bioballs in the downdraft are made from nylon, and will need to be replaced after a year as well. Other then that, the skimmers are acrylic and there's no issues.
 
I just bought this o3 reactor after doing some research about building my own. This one wasn't much more than what I was going to spend to build a diy unit. o3 reactor It should be here tuesday and I'll post back about its quality and effectiveness after I start using.
 
HndMafia I read your post about just buying an O3 reactor.. I cant find one anywhere. Are you modifying a Phos Reactor?

I have been thinking of building one myself because I cant seem to find one online.

I see some post about DIY but they are not very detailed. At best it is a sketch that someone drew.

I have never used ozone and was just curious..

Anyone with some good advice?

(I know about using skimmers but I wanted to go with a reactor due to the fact that everything I have read has them being so much more efficient and the water and air exiting can be run through a nice homemade tube filter full of carbon using some PVC pipe).

BTW not much info on reef central in the DIY on this topic that I can find either. Any advice would be awsome.

HndMafia, looking forward to hear about your reactor - I share the same feeling about lack of good sources for O3 info... I have a microzone 300 plumbed to my deltec ap702, but having the same trouble about the effluent running through carbon.
 
Still tinkering with the o3 reactor. I don't think I have enough water flow and will switch the pump on it as soon as I get a chance. My orp is 70-80mv lower than it was running thru my skimmer, but my skimmer output was pulverizing the carbon. My skimmer is back to a consistent steady dark output since I took the o3 off of it.
 
i contacted aqua c and they suggested that i just drill a hole and put the ozone in through the top and seal it with silicone. on wetwebmedia i read that a good skimmer and reactor are just as effective but a skimmer breaks the ozone down to a point that carbon is almost not needed but suggested to absorb other biproducts of ozone. wetwebmedia has huge threads about ozone that someone messaged me about. very good reads. on my cell so cant reply like i want... good luck guys.. i will keep you posted if i decide to go with a reactor or drill my skimmer.
 
Vinny- Is this the article you are talking about? ozone and skimmers by Fenner After reading it and looking at the graph of my orp levels, I hooked my o3 back to the skimmer air intake to see if my orp would go back up to where it was prior to tinkering with the reactor. I'll keep you posted.
 
Yes that with a few others that he has there.. Redox.. and others.. Lots of good info. I am a bit on the safe side so I will prob make a carbon cup for the skimmers flow to pass thru. I have a home made icetea bottle used for over flow which I have on top of the sump. If it were to over flow it just goes into the sump. A fail safe system. I will prob go with ozotech 100 mg.. dont need an air drier for it and has the most steady output. All you have to do is a periodic cleaning of the unit.
 
Ok a little update. After reading many articles I noticed that a good skimmer and reactor is about equal in how well it delivers O3. A pressurized reactor should in theory work a little better, but the amount of ozone we are using is burned up in a good skimmer and the third Oxygen is dispersed easily into the water.

So I went with the Ozotech Jr 100mg. (ozotech makes 2 one has a variable output and a power button about $170 - $150 more) I also bought a Milwaukie ORP controller and some check valves and an air pump.

I have the Aqua C 120 skimmer and do not have the JG fitting. Steve from Aqua C suggested simply drilling a ¼" hole between the air injection and the water input. Then just slip the air hose coming from the ozone into the hole with some silicone. This will cause the air, water, O3 to react then get mixed in the chamber.

I have pretty clean water as it is. I have UV going and my cleaning practices are silly. I also quarantine everything before it goes into my display. Although I went through all of this, I have a huge outbreak of ICH. I am going to Ozone for a means of disease control and perhaps even a little bit more of a clean look to the tank.

I'll let you know how everything goes. I should get everything in the mail either this Sat or early next week.

I never recieved the ozotech ozone generator in the mail. Found out that Ozotech apparently builds to order and it takes around 3 weeks from time of order. If this thread is still around... I'll post my results.

I have a real bad case of ICH. I am unable to take my tank apart. I have heard that adding ozone can be a miricale cure, but then some say it was of no help. My fish are eatting well and not scratching. They go to the shrimp but dont seem to be suffering at all, thats why I am willing to wait. If they beat it in the display I hope to get ICH low enough to beat it where it is hardly noticable. I know some say it is always present, and some say you can totally rid a tank of it. (I personally believe you can get rid of it)

So when it finally comes in I'll post what effects it had on ICH. Clearer water will be nice also but I am very clear as it is.
 
Ok everything finally came in. This is my first experience using Ozone so I had made some rigs to help hold carbon so I can get the air flow and the affluent to flow through carbon.

On the exiting air I think I need a bit more carbon because the odor of ozone can get strong at times.

I'll post some pictures later (at work now) to show how I drilled my skimmer Aqua C 120 and how I used a chineese food container to have the affluent flow through carbon with a 4 way T section of pipe.

As far as my sick fish, he was doing fine. Eatting etc etc. Very strong. The day I go the Ozone he was laying on the sand.. breathing heavy. I quickly was able to scoop him up and put him in my sick tank.. he is doing well now. Other fish are doing good so I cant see signs of any ICH.

I read on another site that for treating parasites I should bump the ORP to 400 so I have my controller set for that.

I'll put up some pictures later..

IMO injecting ozone into a protein skimmer will require a tall protein skimmer i.e MRC or MTC or any becket injector protein skimmer due to longer contact time. Most of nowadays protein skimmer come with 24" tall will not have enough contact time for the Ozone to properly work because the turnover rate is too fast.

I personally own a large protein skimmer 65" tall with 16" OD body 6 Recirculation Aquabee F-5000 but i decided to use the reactor for many safety reason plus i don't want to take the chance to destroy my expensive protein skimmer over time.

I have done a few PM exchange with BOOMER as well as Billy and Anthony in Reef Chemistry forum and they all agree that i should use the reactor. As for the O-3 reactor goes there most efficient one in the market nowadays is the MTC PRO240D. Now, that bad boy is a bit pricey if you get the complete kit which come with the Carbon Airfilter and the media chamber which will be use for effluent carbon. Another unit that i found for being well build is the Si-am Ocean made in Thailand which is the same one Mr. Ching is using in his monsterous system. But you have to find the way to get it ship to U.S or which ever country you are from.

This weekend i will work on getting my Ozone reactor and U.V sterilizer up and running. I am using Sanders 300mg/h Ozone generator, MTC O-3 reactor, MTC Carbon Air Filter and a custom Fluidize reactor 24" tall for carbon. As for U.V i am running a single bulb HO Emperor Aquatic 150w U.V sterilizer. I will have approx 900gph flow through the U.V and feed the protein skimmer. The Ozone will cycle at 600gph approx 1x turnover rate per hour in my system.

I will post some picture after i finish with the project.
