Who uses ozone?

ok Can you guys tell me what the safe dosage would be. I have a 90 gallon reef tank. I also would like to know if i need to run the return water into a carbon filter.
Thanks
 
Hi victor90,

For a 90 aga, consider about 30 mg/hr piped into the protein skimmer (It doesn't take much at all to get the water clear). Use an ORP controller and shoot for 350. Its a good idea to run your return water through a carbon filter.

As I said before, I dont really look at my ORP or run carbon. The above is the proper way to use O3. I look at my tank and decide if the water needs more O3. Otherwise, I run the lowest amount possible.

Guys, how do you know how much ozone to put into the system?.
IÃ"šÃ‚´ve read some books and they all state that if used in the protein skimmer the recommended dosage is 10 mg/hr.
I have a 300 gal sps reef and IÃ"šÃ‚´m currently using about 10-12.5 mg/hr 24/7 in my skimmer, but IÃ"šÃ‚´m reading that you use bigger amounts of ozone, so how much would you recommend for me and why do you get those numbers?
TIA

The corona discharge units like that one drop off in their efficiency rather quickly in my experience.

The inside of the reactor chamber corrodes in the salt humid environment around the aquarium. With this type of ozone generator you should look into finding an air drier with it-- Not sure if that will work with this unit since it includes the air pump.

o2manyfish,

I saw those units too and was going to give one a try. I have a double fish room and have the ability to put the unit in different room (plus the fact that I have a fresh air exchanger on my main fish room). Are the corona types only impacted by salty environments or are they just not a good design and the salt makes it worse?

Mhurley,

It depends on the design of the ozonizer. The old sanders, you could dissassemble every couple of months and use a wire brush to clean it out and. The Ozotech are a sealed can and not so easy to open and clean.

The one's I now have are the same as the RK2 ozonizers. they work like a spark plug. Anytime you can get electricity to spark and jump a gap, as the electricity jumps through the air, it causes the o2 molecules to become o3. There is no maintenance on these.

They do make a slight buzzing sound. But I wrapped mine in a towel and they are silent now.

yeah, Shanghai, so warranty claims are out the window, but it is cheap and they seem to have good feedback. plus I only want to ozonate a 20gal tank..

What will happen if I don't run the return water into carbon?
Has anybody ever tried the red sea or the coral life?
Thanks
 
Victor90,

I used to run carbon (for about 6 months) with the ozone and suppose you probably should, but I don't. I've only run O3 for about 2 years without carbon and nothing bad has happened.

I use the red sea 50mg/hr unit. It works great.
 
I have a dumb question about ozone .... if among the benefits is water clarity, is there a need to run carbon as well (for the purpose of polishing the water, that is)?
 
The humidity is so high in VT that my air dryer is spent in 3 hours. So I dont use it. Its good to have one as it increases the efficiency of the ozonator. I need an electrical air dryer. Last I checked they were like $500 or something crazy like that.
 
delphinus,

Other people might jump in to anwser this question.

I've found no reason to run carbon for the purpose of clearing the water (when running ozone).
 
Repeating this since it seems to have been missed...

I started dosing ozone a few days ago.. so far im at 15% of 200mg/h for 2 hours a day (12pm-2pm)
My orp has climbed slowly from 250 to 280 in about 3 days.
When i first monitored my orp 6 months or more ago it was around 320 at the time.
Now it seems low. I do have a case of cyano/dinos right now

Should I leave my settings be and hope it slowly comes up?
or up my dosage time (or %) to get in the 350ish range?
 
You can if you want. looks like it's slowing coming up when using the ozone anyway. Does the water look any clearer yet?
 
Baalz,

Is this your 75 or 180? From my research, you could run that dose (30 mg/hr) 24/7 on your 75 without any problem. More on the 180. I would rely on your observations of water quality and the health of your livestock more than the ORP reading. Use the minimum amunt/time that gives you the results you want.
