Here's the Ozone generator I've bought...

It's on it's way, so I'll do a review of it, and maybe a video of setting it up. From the pictures I've seen it seems very straight forward, but I'm not sure how it's calibrated...

Cool, if you're going to start a new thread could you also include cost of components?  Co2 bottle generator,  probe, is there a regulator on the bottle?  Will you be getting new bottles of gas or haveing them recharged?

I should really sort this out!!

CO2? I'm not planning on running a PH controller? I won't be using CO2 at all.

K, looks like I should read up on ozone!

A CO2 bottle on a marine tank might be either on a PH controller, where CO2 is percolated through the water to lower PH, or on a calcium reactor, where the acidic CO2 dissolves the calcium into solution.

Ozone is just piped through the skimmer, the skimmer is an ideal reactor chamber for it. You could just use an airstone, but the skimmer is too perfect for the job already.

The ozone gas is a super powerful oxidiser, and so it increases the oxidation reduction potential of the water, and sterilises it too. You measure the ORP in millivolts with an ORP probe, and a reading of between 300 and 350 is a good range, although some run as high as 395. Any higher is dangerous.

There's no consumables with ozone, except for the silica gel air dryer (as the input air needs to be very dry), and when that's full, you can either microwave it or replace it.

I have read that,

I read this twice now!

Part 1: http://reefkeeping.com/issues/2006-03/rhf/
Part 2: http://reefkeeping.com/issues/2006-04/rhf/
Part 3: http://reefkeeping.com/issues/2006-05/rhf/

Why'd you ask? If you're looking to read up yourself, the TSB article is a good overview, but I've used ozone before, so wanted to try to get to grips with the nitty gritty, most of which still goes over my head though, but it's good to read from a trusted source, Randy Holmes-Farley...

Have I read somewhere that some types of plastic are not compatible with Ozone and some skimmer parts might have to be upgraded?

For some reason I'm able to use the links (it's not a forum thing!), I'll print em out in work tomos, thanks Mike. Will have to check if my deltec is ok.

Yep, that's right. Ozone is hugely reactive, and things like natural rubber (think of elastic bands that go brittle over time), will degrade in a year with O2, so O3 will rip through them in hours/days.

Silicone is Ozone safe though, and all the rubber rings in my skimmer are silicone.

I can't find much info on it, but as acrylic is ozone safe (as far as I can tell), the Bubble Magus skimmers should be ok. If any parts aren't, well I'll soon find out won't I!


There's a list of materials and their ozone compatibility, I'll go dig it out.

Mike, When i send your frags ill send some silica gel over as well if you want ? (the colour changing stuff) ref drying i would recommend using an oven to dry it off. by a cheap metal tray from tesco and pop it in the oven. We use it at work with our Ranarex gas gravitometers. Not sure if it's expensive or not.

The ozone generator I've bought comes with a drying chamber, a 200ml chamber full of that colour changing silica gel that the air is drawn through before it goes into the unit. Thanks though, I'll keep that in mind if mine degrades or something.  :glad:

The only thing I'm not sure about is if the draw of the Venturi alone is going to be enough. I imagine the airflow through the skimmer will be so much reduced by the resistance of the extra airline, and the air dryer (the generator itself won't restrict, it's just straight through) that I might need an air pump too. I've got one but it's not very highly rated...
