ozone and asm skimmer

[120gallons]

Anyone have any pictures or info on how they inject ozone in an ASM skimmer and where to put carbon, etc?

[Dentoid]

I have a T-fitting in my Venturi intake hose. In this picture the ozone tube is not attached, but I have it plumbed into the intake.



The bag of carbon sits on, or is adapted around, the adjustable output tube where the water is released.

Also the small ozonizers units (100mg/hr) that are made for the hobby have little if any risk. I do not have carbon on my out put tube and have had no problems.

I can get better pictures when I get home from the office, if you would like to see more.

Doc, are you testing for orp? There are some great articles i know of if you are interested.

[120gallons]

Do the hobby units work as advertised? For a 120 gallon with another 40 or so gallons in a sump, I think the 100mg unit is probably a good size, correct?

[Dentoid]

Yeah, I have an ORP probe and I keep an eye on it. At first I was concerned, but with the little rinky-dink Red Sea 100mg/hr unit I have, I couldn't overdose a glass of water!

Thanks for the offer on the articles, but I've already researched until I'm blue in the face. Besides, it's boring reading.

Frankie are you using ozone?

Yes, the 100mg/hr unit is sufficient for 120 gallons and IMO is safe.

[Frankie]

Nope. I just don't see the need for it to be honest on a system as small as mine. Its just a total of 197 gallons.

Now the question is where the heck to get a ozone resistant t fitting? I can't find them anywhere.

[Frankie]

From the picture Doc has up top, you can pick that up at home depot in the plumbing section.

[Dentoid]

Yeah, I purchased that fitting at Home Depot. It's probably not ozone safe, but if and when it rots I'll buy another one. As you can see in the picture the ozone tube is inserted into the T-fitting and the Venturi sucks the ozone into the skimmer. I never smell ozone in the room!

hey i was just wondering can a 100 mg/hr work a 210 ok and what are the tank limits of a 50mg/hr and a 100 and a 200 i have been looking all over and i cant find out any where

[120gallons]

How do I ensure I don't have ozone spilling into the air. I think I may by smell. I have carbon over the outlet and top of the skimmer. The only thing I can think of is I have the air pump too high....but even that doesn't make sense.

[Dentoid]

You don't need an air pump if you have it T'd into the Venturi intake tube. The Venturi will suck it in. The pump is probably blowing it out the end of the Venturi tube

[120gallons]

Ok, changed it. How much airline from the generator to the T do you have? Do you have a check anywhere in the setup (I don't).

just an FYI for people considering using ozone. all water thats exiting whatever you choose to use as a reactor(skimmer, O3 reactor) should be actively treated with GAC (carbon).the carbon treatment isnt intended to remove excess O3 but product's of O3 reaction with bromide. bromide is a common element in sea water, salt mix's and calcium additives. O3+bromide can/will create hypobromite, bromate, bromine (bromine is just like bleach)
