hooking up ozone to skimmer

I just received my ozotech ozonizer today and I'm setting it up through my xp-1000sss. I got ozone safe tubing and I'm T'ing off my venturi tube so that it will suck air through the ozonizer. Should I plug the other end of the T? I can feel the air being sucked through the ozonizer but it doesnt feel that strong. Would there be a problem if I had my skimmer only suck through the ozonizer? I have my ORP sensor hooked up to my APEX to shut off at 380 and on at 340 to avoid over supplying o3.

I had it set up but I turned it off for a second. I believe I can smell the ozone in my sump area. I put a cup of carbon and put it in a mesh bag and placed the bag on top of my collection cup. I only have the ozone unit set at 22mg/hr and no air filter so probably only running 10mg/hr. I've read that ozone can be lethal, how much ozone would it take to make my condo dangerous? I know that u shouldnt smell anything, should I try more carbon on top of the collection cup. Ozone smells like metallic air right? Or like a spark smell?

This is my set up....I have 1/4 tubing from ozonizer to an extender 1/4 to 3/8 tubing. Then to the T. The T has 3/8 tubing going up sucking in air and then the down direction is to the skimmer pump.

The ozone unit came with a check valve and in the instructions they recommend using the check valve..is this necessary?
 
also..can I tape off the holes in my collection cup with electric tape or something to eliminate o3 coming from my collection cup..or do those holes act as something?

I've read that a faint whiff of o3 around the skimmer is alright, but that you should not be able to smell it in the room. Correct? I was smelling around the skimmer area, I was expecting there to be NO smell.
 
What height in relation to the skimmer is the ozonizer? Definitely use the check valve by cutting a very short piece of the ozone safe tubing and feed that over the outlet of the ozonizer then paying attention to direction of flow insert the check valve into that short piece coming from the ozonizer. The other end of the check valve can then be inserted into the tubing going to the skimmer. I'm not familiar with your particular skimmer but chances are that if you tape the holes you'll stop the skimmer from working.
 
i found out that the check valve is used to prevent reverse syphon into the ozone unit....I dont see this happening. The T is above the water and the top of the T is open to air, so no reverse syphon could happen.

should I close off the open T end and suck all the air directly through the ozone unit?
 
I would say yes to that question, or you will not be pulling the air through the unit - path of least resistance. O3 has a "sweet" smell to it, and you should not be smelling it throughout the house for sure - I run mine through one of the pumps on my skimmer with no "T", but directly through it. as far as laying carbon on top of the unit, I would recommend using a filter bag (think Chemi-pure) and making sure it is really over the holes well... I have seen some lids that are more adapt to using carbon for "smell" that actually have a chamber built into the lid for doing just that - think double layer cup, one for waste, one for carbon filtration. Keep the setting low for now, and gradually increase it - it will take some time to effect ORP. Are you also washing the effluent from the skimmer through carbon? O3 can leave boron and some other heavy metals as a byproduct... only if you are dosing heavily... Randy Holmes Farley has written some excellent articles on the use of O3, I would suggest some research on it for some comfort.
 
I came to the conclusion that I should be only sucking throught the ozone unit. Thanks 108reefer for all the advice. I think some ozone was leaking out of the open T making my sump area smell. BTW...I hate the smell of ozone. I cut up an old pair of boxer shorts and made like a bean bag and filled it with carbon to put on top of my collection cup. As for the return of my skimmer..i put some carbon in a mesh bag and put it around the exit...although on the xp-1000sss the return is fully submerged under water so no air exposure is there.

I'm glad to hear that it will affect ORP slowly..when I was running it yesterday my ORP wasnt moving so I got confused. I'm starting at the 1 setting, which on the manual says 22 mg/hr, but like I said I'm not running an air dryer so probably half of that is getting through, which sounds about right for a 75g total volume tank.

I'm anxious to get this up and running to kill my dino's, but I want it to be safe at the same time...anything that has possible effects to humans I take very seriously.
 
everytime I start up the ozone unit, I can smell the o3 in my sump area. I have the air feed to my skimmer directy hooked through the ozone unit. I put some ROX in bag and placed it above the holes of my skimmer. Any other idea's why I would be smelling the o3 so much. I have the level at 1.
 
I want the smell to go away..but my main question is this....

Its currently running at 22mg/hr....is this enough ozone in the air to effect me? I think I've only had the unit running for maybe 2 minutes...maybe four 30 second intervals. I've read on WWM that it takes pretty bad misuse to negatively effect humans.
 
I am running ozone for 30 years and never smell it unless I disconnect a hose. All of it should be used up in the skimmer otherwise you are wasting the ozone, using too much or your skimmer is not efficient enough
 
hmm...I def smell it.

my reef octopus skimmer is the sump saver version..meaning that it has a smaller reaction chamber, could my skimmer not be able to effectively handle the ozone?
 
It's set at 1..i cant go any lower.

I was reading about maybe making an ozone reactor using an aqua medic Co2 doser. I've heard of one person using this. Has anyone else tried this. I'm thinking my skimmer doesnt have enough contact time..thats why I can smell it. I mean I get a pretty strong wiff too

is says that this built from quality acrylic...would this be something to use my ozone through? I'm thinking maybe injecting my ozone into this...electric taping the holes in the collection cup and setting the skimmer level so that it doesnt go to the collection cup. So it just tumbles in the chamber without skimming.

perhaps even when clogging the holes in teh collection cup..pouring carbon into the collection cup to filter out any extra ozone going up.
 
t4zalews, Not sure why you are getting such a smell with a low setting... First let me say that you should really have an air dryer before the unit - without it will drastically shorten the life of the reactor! I made one out of some 1 3/4 pvc, a couple of end caps a drill and some very course foam - and of course some silica beads... Ok, no on to the smell - I am not sure I get how you are covering the holes on the top of the skimmer? get some fine mesh bags (think nylon stockings) and use a healthy pile over top of the holes - if you have to maybe make a lip around the top of the collection cup to help hold it in place - you just can't restrict the airflow. I will look up a picture of your skimmer to see if I can offer any more insight...
 
I think I'm getting such a strong smell because the bubbleblaster pump pulls in so much air and since I have the sump saver model, the main chamber is only about 7-8 in. high. I dont think the ozone has enough time to dissipate into the water. I've looked up ozone reactors but there are only a few and are very expensive. If that eshoppes skimmer is ozone safe, I might get it...I'd have 20" of reaction time and I could clog the top of the riser tube with carbon...making the ozone pass through it. I'd set the skimmer to break apart early so it doesnt skim. It would be positioned after my octopus which really pulls out the majority of the crud.
