Ozone Users...Need Help

[lionspride]

I have been reading alot about ozone and want to use it. The only thing is not exactly sure how to set it up. I'm going to put in my skimmer. I always put my carbon in a bag and put it between one of my baffles in the sump before the return. Is this good enough? And do i have to rig something up so that the air exiting the collection cup goes through carbon? Please any sugg on setups and a safe way to use ozone. I also heard excessive ozone is bad for humans to.

Its a good idea to filter the post air through carbon. If your o3 input is adjusted correctly there shouldnt be any 03 escaping as it will be used up. The carbon should be dirrectly at the skimmers water output . The main reason for the carbon is to catch any bromide that is produced by the oxidation of the 03. It would be better to dump the exiting water over the carbon . This way there is no chance of water passing by unfilterd by the carbon.

I'm not a fan of using a skimmer because the contact time is too short, the water flow is too high, and the air flow is too high. That said, many folks do it, but I would certainly treat both the water and air leaving it.

I discuss setups in the second article below:

i know that coralife makes a reactor but you said it was not a great product, is there another reactor that you could recommend?

 

[Randy Holmes-Farley]

I recommend my DIY, or the every expensive one that I note in the article. Other than those, I am not familiar with any other good choices, but there may be some.

I have two of the ones that Randy recommends in his article. But both the water and air output of this should go through carbon. MTC if anyone is curious.

lionspride, I have used ozone for many years. In that time I have used nothing other than etss skimmers. Since etss skimmers are not ozone friendly I have never used them in any ozone application. I always run the ozone through an mtc carbon reactor and I could not be happier with their performance. I must say on this topic to get all the information about ozone that you can, and then figure out how to best set it up for YOUR system. Last but not least, go slow. HTH.

 

[snorvich]

Amen to going slow. My ozone system is a fairly elaborate one, the one MTC sells composed of an ozone reactor, air/carbon, water/carbon, ozone producer (ozotech, recommended), and air pump. Keep in mind that not all reactors or protein skimmers are "ozone safe". Be sure the tubing you use IS ozone safe. Be careful about letting ozone into the area around people.

I have a DIY ozone reactor that seems to be working very well so far. Its a basic design like a air stone skimmer. All made of 4" ABS and PVC. Its 5' tall so the contact time is good. Basically a maxijet 1200 pumps water in near the bottom and then water exits closer to the top. There is also a removable carbon container ontop to catch any ozone getting into the air. The water out form the reactor is run through carbon as well. The ozone is injected into the reactor using an airstone and neoprene tubing. Like I said, just like a very basic airstone skimmer. It takes about 45 seconds for the reactor to fill up and for water to leave the unit, so the contact time is decent. Much better than a skimmer anyways. It only cost about $50 I think.

How offen do you change the carbon for water and air exiting your ozone reactor?
