using Ozone

Pescador · #1 09-12-2006, 05:50 PM

Thanks for the info, I'll give it a while to break-in.

Also the readings vary depending on what the set point is at. The instructions say to take the readings with the set point cranked all the way up.
I get 165 with it cranked up and 48 with set point at the lowest. This is with the selector switch in the reading position. Does that make sense?

Also, after a ton of searching I finally found a reactor for pretty cheap.
It's 22 inches tall and it looks like it comes with same shredded plastic media as the MTC.

They are drop shipped from Aquarium Life Support Systems

They don't take Canadian credit cards, just cert. checks or money orders.

I'm going to run the output through a Phosban reactor filled with carbon.

Sound like you are all sorted out. Pressurized reactors are 100% the way to go over using a skimmer. Make sure you filter your air line OUT through carbon as well.

Does your system come with an Air dryer?

Please keep us updated how this works out for you. I am interested in this as well rather than running through my skimmer..

I did get an air dryer and I'll have to figure out a carbon air filter for the exhaust when I get a better look at the reactor.

What are you using for an air pump? Is it adjustable output (like a Luft) or did you have to use a valve to adjust it?

I'm still not sure how you can pressurize the reacter and have an air exhaust.

Your MTC is an awesome piece of hardware, thanks again for the tips.

No worries, and thanks.

I do use a Luft pump to adjust pressure in the chamber actually. What happens is that as the pressure build, the air escapes from the chamber and into the Carbon filter.

Is it possible to push the water into an ozone reactor and then through a fluval full of carbon to get rid of excess ozone?

Wow you guys are sure making this sound complicated... !!! I just run mine through the skimmer... run the effluent from the skimmer through a bag of carbon I change once a month... and the pressurized collection cup I built lets the air escape through another pack of carbon .... If ozone was this hard I wouldn't be running it!

LOL. You are right. Ozone does not have to be that hard.

That being said though, running it through a pressurized reactor increases contact time with the water in a huge way, bringing along a lot of added benefits.

From ReefCentral:

"Skimmers water and air flow rates, and even their engineering design itself, are optimized for skimming, not for ozone injection and reaction. The longer the ozonated water has to react, the more oxidation of organic molecules can take place. This is not a design criterion with skimmers, where the air/water contact time is maximized, but the water alone is not held for any purpose. If the water's flow rate is too high, and hence its turnover rate too high, the concentration of ozone in the water, and the contact time for it to react with organic materials, may be less than optimal."

If you are going to use a skimmer for Ozone

"Select a skimmer that allows a substantial volume of water to be contained within it, so that the ozonated water is not immediately swept away and passed over the GAC (where the ozonation reactions largely end)."

I think it might work as long as the Fluval did not hinder or speed of the flow. I guess you could just leave it unplugged. Actually, that should work great!

That's how I have it hooked up right now and it seems to do a good job. Originally I had the fluval turned on but the flow was far too fast. The only thing I don't like is that I'm using a Coralife Ozone Reactor and the air bubbles produced by the airstone don't seem to discipate that much throughout the bioballs. The air usually just travels straight up the reactor and then into the fluval.
