Hi,

I need some suggestion to pick up an ORP probe for Red Sea Ozonizers. I plan to order Red Sea AquaZone Plus 200 mg/hr ozonizer and Red Sea Air Dryer 500 g, but not sure which brand of ORP probe fit my need. I assume ORP probe can directly connect to Ozonizers, and not require additional ORP controller, right? Which probe I should pick? American Marine, Neptune, Aqua Medic, or Octopus?

Thanks,

shih87

American marine works well.
Also buy the larger dryer or even better get two large ones as the beads saturate fast and require at least weekly regeneration.
With the small dryer I had to regenerate every two days!

The aquazone Plus has the controller integrated in the unit, that is what the ORP probe is for and conects directly to the meter portion of the ozoniser. No need for extra controller.

Hi jdieck,

Thanks for the promptly inputs, will definitely buy larger dryer. Some additional question after read Red Sea manual. In the manual, the recommended configuration as below...

Air Pump .... Air Dryer ... Ozonizer ... Protein Skimmer ~ Aeration Chamber ~ Activated Carbon Filter ~ tank.

What is a Aeration Chamber? Is a regular sump good enough for aeration?

Thanks,

Yes the sump section were the skimmer drains acts like an aeration chamber, in other words allows for some time so non dissolved and un-reacted ozone can partially vent but Ozone is so reactive that I doubt you will have any unreacted on and if so, it will usually be vented trough the skimmer vent.
My recomendation will be that in addition to providing a carbon bag in the area of the skimmer discharge you also provide for means so the skimmer vent also passes trough activated carbon.
If you have a waste collector with carbon in the vent that will sufice.

Hi jdieck,

Thanks again. Someone mentioned Ozonizer to Protein Skimmer will significant reduce skimmer productivity, and suggest Ozonizer connect to a reactor instead. Is it true? What reactor he refer here? calcium reactor? is the concern above the reason you suggest the skimmer vent passes trough activated carbon?

BTW, your signiarue of "Did I write what I wrote? What the heck am I talking about! Well..... Nevermind." scare me on what we discussed here :)

Thanks,

Take the signature as a form of modesty :lol:

In reality there are reports all over the place in regard to skimmer productivity, some say it will increase productivity, others that will reduce it and others did not noticed any change.
I personally noted an increase in performance wit as small dose as 30 mg/hr.

More of an issue is the productivity of the Ozone when using a skimmer. The contact time of the ozone in the skimmer is relatively short and a good portion is vented trough the skimmer vent and although some ozone is wasted the 200 unit is a lot more than what you need for your 120 gal tank. This venting is why I recommend to use carbon in the skimmer vent, to remove that ozone.

The reactor they refer to is really one designed for Ozone, as far as I know there are only two in the market, one is crappy and does a very poor job and the other one (It think from MTC) is very good but requires a lot of periferal equipment (High pressure water pump, high pressure air pump etc) as it works pressurized to increase the ozone solubility.

Here is a good three part article on ozone you can learn a lot more:

I have a redsea unit also and I use the pinpoint ORP probe. works just fine.

ioreefer45, thanks.

Ok, now I am more concern after read "Ozone and the Reef Aquarium, Part 2" regarding the human safty issue. I have my 120 tank in living room, and plan just put Ozonizer on top of the canopy. Is it too risky? Do I have to put it in my garage? but I really don't want to drill a hole over plywood between living room and garage ;-(

The Ozoniser is not an issue, the issue is potential Ozone released from the skimmer into the air so if you have proper activated carbon in the vent you will have no problems.
Also insure you use an Ozone resistent tubing for your conection from the ozoniser to the skimmer.
If your skimmer has a single vent that you can hose the air out of it then in the Equipment part of the article (I think part three) there is a drawing of the skimmer waste collector I use that will allow you to collect the waste at the same time of filtering the vented air with carbon.

jdieck,

Thanks. I have also ordered Ozonizer tube from Marinedepot as below....

"The Ozoniser is not an issue, the issue is potential Ozone released from the skimmer into the air so if you have proper activated carbon in the vent you will have no problems."

Can you explain how I have activated carbon in the skimmer vent? Do I put activated carbon in a filter media bag and have Skimmer out water drain thought the bag? Sorry if the question is too stupid.

Thanks,

It depends on how the skimmer is venting its air after it has formed the bubbles.
Can you tell me what skimmer are you using or a picture of the collection cup?

hi jdieck,

The one I have is Deltect 701 and here is product link...

A bigger picture can be found at http://www.proteinskimmer.com.au/index.php?main_page=popup_image&pID=39&zenid=4e06babc64641013f918d7b2971dee6c

I will take a picture of my setup after back home from work.

Thanks,

That skimmer will vent trough the ouput pipe (The portion pointing up and trough the small holes? on the top of the collection cup.
For the small holes you can put a small bag with activated carbon on top of each.
For the vent pipe you may need to adapt a carbon container similar to this one that has an entry on the bottom you can connect the pipe into. The air will vent trough the mesh surounding the cartridge.

Hi jdieck,

Thanks again and sorry for delay of picture posting. Here are my skimmer pictures. The fist one show two small holes on collection cup cap, second one shows skimmer in my sump.

Thanks,

Yes, just two bags one on each hole and a carbon container on the vent pipe will take care of Ozone venting. You will also need some carbon (a bag) near the discharge of the skimmer.

Hi jdieck,

One more question.
What kind of air pump you would suggested? What I have handy is "Aquarium Pharmaceuticals RENA Air 200 Pump", http://www.marinedepot.com/ps_ViewItem~action~view~idProduct~AP7215~idCategory~FIARPIAFSO~category~Single_Output-Adjustable_Flow-Plug_In-Aeration-Saltwater_Aquarium_Supplies~vendor~.html

Not sure if it is enough.

Thanks,

You can try it and see how it goes although I would recommend a high pressure pump:

Well, some issue pop-up.

After explain to my wife, she still not allow me put equipment on top of canopy, she said I should put it in garage since she has concern of leaking O3 in liviing room ;-(

This means I have to drill hole on wall or find way to convience her.
Stay tune.

The amounts of Ozone used do not really pose a treat specially using carbon.
