I have been reading about the benifits of ozone and have read that the skimmer is not the most efficient place to introduce ozone. People talk about using a ozone reactor, but I have had no luck searching or pinning down a part number. Please point me in the right direction. I have a 250 Gallon system with ORP controller, air dryer, and Oztech Posiden Generator, and need to find a good reactor for my system. Thank you for your advice.

This is a good one:

On the site they offer a reactor, carbon air filter, and a CA7? They do not list what the CA7 is, is this just a carbon reactor that is upflow? If setting up the system as in their diagram would this work as your tank carbon reactor as well or should the ozone system be seperate? Thank you for your help, any pictures of your DIY?

Perhaps the use of ozone with skimmer is based more on practical ease, since air is drawn into the skimmer thru the ozonizer. Is this true?

Is there chemical reason to use ozone in conjunction with skimmer? Ozone converts ammonia to nitrate, but the skimmer is to reduce the generation of ammonia, so ozone seems to come too early.

I like your DIY reactor Randy. Its cheap and easy to setup.

My fault with using a skimmer is the contact time is shorter than most reactors and the water flow is usually so high that it may be hard to adequately pass the effluent over GAC before getting back into the tank to remove highly oxidizing species.

On the site they offer a reactor, carbon air filter, and a CA7?

I didn't see a Ca-7. I saw an SR-7, which presumably is a GAC containing reactor, but I've not seen a description of it.

I do not know why they show the air exhaust going to the sump. Maybe it sometimes gets water in it.

The GAC that is exposed to high ozone water may not be especially good at binding organics, as the ozone will break them back apart. I run a separate canister of GAC for treating tank water, but if eh GAC reactor is large enough, then any part after the area where the ozone is effectively removed should work like normal GAC.

FWIW, its described in the second article:

Ozone and the Reef Aquarium, Part 1: Chemistry and Biochemistry

Ozone and the Reef Aquarium, Part 3: Changes in a Reef Aquarium upon Initiating Ozone
http://reefkeeping.com/issues/2006-05/rhf/index.php


The only thing I’ve changed over time is increasing the GAC treatment from 4" PVC to 3 nested IO salt buckets for greater capacity and less chance for it to clog.

The water/air/ozone mix enters the middle one and air goes through many small holes in the bottom of the top one, through 1-2" GAC, and out to the room air.

The water drops through 2-3" of GAC, through many small holes in the bottom of the middle bucket, and then down through a single hole in the bottom of the bottom bucket to the sump.

I have been running fairly heavy ozone w/o any carbon on the effluant for about 5 months now, and have not noticed any problems. However, the effluent is returned to a huge sump and this is on a 350 gal system. Perhaps the effluent ozone is simply reacting enough with the water to not require absorbtion by the carbon.

Is it generally true that literature overemphasizes the risk of excessive O3 to aquarist and livestock?

To this point, Paul B has run ozonated water into his refugium which is like a long trough (without GAC). The end near the ozone has little growth, and things grow better down the length.

The oxidants are depleting themselves on organics and such down the trough, but where it first enters, it is clearly less amenable to growing organisms.

Depending on the size of your tank, the aqua medic 1000 CO2 reactor works very well as an ozone reactor, and costs 1/5 the price of the MTC reactor. I really like that MTC reactor though. If money were not as a much of a concern I would be running one.

I have been thinking of the best way to set up for ozone on my tank. I am using it now, through my skimmer, but I will not be doing that for long.

I thought this this may make a nice little ozone reactor. You could run the ozone into the first canister, and have one of the refillable di canisters in there full of pvc shavings or something. Then when it left the first canister, you would be able to pass all of the effluent over carbon in the second chamber.

I was actually considering the same thing, if you do it, let me know how it works out.

Just bought an ozonator. Studing up on it. Why is a reactor better than the skimmer?

A reactor isn't always better than a skimmer but can be because of lower flow through and better saturation when pressurized (depends on the size too).

Lukinrats, are you planning to add some sort of venturi or airstone? How will you deal with the pressure build up from injecting the gas?

If I did this. I would just probably use a maxi jet pump, and try to inject the ozone into the venturi. If it is not strong enough to pull the gas in, then I would probably just drill a hole in the top of the reactor, and place a line that will bubble into the water.

I would not use a pressure rated air pump, so I am not all that worried about getting a buildup inside the reactor. Whatever is injected will just escape with the water that comes out of the carbon chamber

I know that this supplier has been testing a new low-cost ozone reactor for about a year. They are in our local club so we know they have put a lot of time into the R&D.

http://www.avastmarine.com/cb/


If you get in touch with them, you might be able to get an early version. As you are noticing there is a real gap in the equipment market here.

I thought I would post this link from our local club regarding a substantial R&D effort on this.

Someone is using a Aquamedic 1000 CO2 reactor for ozone. Any thoughts?

The link in Randy's article for the DIY plans is dead. Anyone have a link that works?
