Ozone Units

Has anyone any experience of The Ozone units that are on offer at the moment.

Need more info but they sound good??

Hi there Valleykoi. I've read about them and am very intrigued, let's hope someone can give us a bit more info

which units are these peter?

There are some small ozone units available...as well as large.

The smaller ones seem great for the QT tank and are quite cheap.

The ozone helps with knock and sores and appears to make the water sparkle.

I believe it is an air pump that places something through air stones into the water...ozone..but do not know much more.

I need to do some more homework.

If you are talking about the micro ozone units then save your money - the amount of ozone that they produce has no or very little effect on the quality of the water. To gain any effect from ozone it needs to be of a strength (please correct me if I am wrong) of 1 gramme per thousand gallons of water and also mixed appropriately if a reaction chamber before it re enters the pond - this needs to be monitored using an ORP/REDOX meter to ensure that overdosing does not occur - a lot of scare stories out there of fish wasting away when moved into an ozone free pond or having no immunity - I am yet to see the evidence of this - Ozone has been used successfully in fishkeeping for many a year

This is why the forum is so useful.

You read on one that these are the best thing since sliced bread and then...

I see so if koi are kept in ozone treated water then if they leave it...bye bye...or maybe.

No Peter...some dealers have suggested this but there is no evidence or at least no published evidence. It would be the equivalent of saying if a baby needs to stay in ITU when born for some time then when it is introduced to the outside world it will be attacked by all sorts of germs.
the common misconception of ozone is that it creates a sterile environment...this is simply not true as to create a sterile environment means to create an environment totally devoid of ALL life forms including Koi. Don't get me wrong this can be achieved by using high doses of ozone continually without monitoring but as I said your koi or other livestock would be dead

Your Comments...

Seriously he (Richard) is way off the mark with that comment, if you dosed a pond at
1gm per thousand gallons you would probably end up wiping the lot out !
I have had a huge effect from the little 200mg unit on the 500 gallon tank plus
about 100 gallons of filter so 600 gallons in total. I would say that 100mg per
1000 gallons is more like the dose should be.
I bought myself an ORP/REDOX meter and when you think that Sterile water
using Ozone would read 700mv. Mine has never got above 250mv and the effect
is really noticeable. And thats keeping well within the safety limits.
Larger outpur units are available but personally I dont think they are necessary,
especially when I have seen what a 600mg unit can do on a 6500 gallon pond
at Mikes.
There is a misconception that Ozone is going to create a Utopia for Koi, but that
has never been my aim. I wanted colourless water, sparkling clear and a method
of reducing to almost zero the bad bacteria and as many parasites as possible.
So far so good.

the actual recommended dosing is 150mg per 1,000 litres
an ORP/ REDOX reading of 250mV only means that your filter system is working adequately - quality water would be more in the range of 350mV
for instance my marine tank has no ozone and is currently reading at 295mV

This is all very interesting!!

I have the chance of being a stockist of these at the early stage.

Still doing my homework.

Any more comments??

you mention you have the chance of being a stockist - can you tell more about the product i.e., what type of ozone generator (corona discharge etc) how it is mixed with the water and what controls you have on it?
