Who uses ozone?

Thought I would give a heads up to any other MRC skimmer owners running ozone. If your skimmer has the quick release option, the o-ring in the spears union is NOT ozone safe. My MR-6 has this union and it started leaking after only a few months of running ozone. At the moment Andy is checking on a replacement o-ring. He says that these o-rings are Buna-N and the ozone safe o-rings are EPDM. Can anyone else confirm which one is safe? I heard the exact opposite in another thread.

BTW, FWIW, I cannot see any visible damage, deterioration, hardening, or brittleness of the o-ring. All I know is that it didn't used to leak and now it does after a few months of ozone use. None of the flange o-rings are leaking. Andy said the flange o-rings are EPDM.
 
I want to get an ozoner but i still have the problem withe the protein skimmer thing. I have an ETSS 600 skimmer. Does anyone know how else i can hook up an ozoner without going to the skimmer or does someone know how to hook it up to the ETSS?
And is carbon necessary? I dont use it now and i really didn't want to start

Simply feed the O3 into the air intake on your venturi. If your skimmer discharge first goes into a large enough refuge tank it should dissipate all the O3 quickly. The carbon is really for insurance to keep excess O3 from entering your tank.
 
If you keep the ozone flow down to 20-30mg/hr, you will stay well within most skimmers ability to burn it up without putting into the sump or air. I have a total water volume of 150 gallons and 20mg/hr is plenty to raise my ORP as a gentle rate.

Low doses over extended periods make more sense than big doses intermitently.

Just an opinion.
 
I posted in one of the other ozone threads but wanted to see if anybody here had any more to say. I think I'm going to build a ozone reactor as my ETSS reef devil blows off too much O3. Does anyone have picts of their reactor, I want to get a few more ideas before I build. The main purpose of the reactor as I see it is for O3 to water contact time, correct?? What is the life of O3 in water, I've heard 30 sec and then I've heard 3 minutes, can someone clarify this for me. Thanks.

Life depends on how much material it has to contact and oxidize. If there is organic material in the water, O3 is very unstable and will be used up in seconds. Any unspent o3 will be discharged, but it also gets used very quickly if it contacts any organic material it contacts on discharge. It will make rubber and plastic crack.

I'm not sure what you will gain, beyond feeding it in to the skimmer, by installing a separate reactor. If the water in the reactor doesn't have organic waste nothing will happen. It is simplier to just add a very small carbon container on the skimmer air discharge to absorb the excess O3 and or reduce the O3 generator output so you don't smell it.

You don't need to feed a lot of O3 to clear the water. The fact is if your smell O3 around your tank while using it, your are feeding way too much. Just reduce the input rate so you don't smell it. The easiest fix. The small amount getting into the room is not dangerous.
 
ldr- my generator is on the lowest setting. the reactor feed will be ~100-200gph and will be coming from my return pump so it will be the same as any water that would enter my skimmer. The reef devil just isn't the best (or easiest I should say) skimmer to retro for ozone, so I figured the O3 reactor would be more efficient and I thought a better method.

It is easy to feed O3 into your Red Devil. Just bubble O3 close to the high pressure feed pump suction, if it is sitting in a sump, so that the bubbles are pulled into the pump. The small amount of O3 gas will have little to no negative effect of the pumping capacity.:rolleye1:
 
Not much different than the acrylic or pvc reactor you plan on building as an ozone reactor. Most plastic isn't affected dramatically by O3, and if it is it will take awhile to cause it to fail. They feed ozone use plastic lines, pumps, and skimmers with very minor affect right now on all system that use ozone. The vinyl lines will get hard in about 6 months and the acryclic and pvc will have little noticable affect. I wouldn't worry about it. About the time they are wornout, or you lose interest in the hobby, it may need to be replaced .:p

I also have ETSS downdraft and don't know how to run it on Ozone but its probally explained in the instuctions of the ozone generator. Etss is such a major pain in the butt. You need to raise the water colum and shake the foam out, it won't skim wet.

I try to use ozone in my old ETSS 800, is so much air goes thru the skimmer you get very minimum ozone reaction from it and you better have some kind of filter with carbon in the air out flow or you will kill your canary if is in the same room with the ozonizer :lol:
