Ozone and ICH

[howman]

My tank has ICH. It did a job on my tangs and angels. I have removed most of my fish into QT....but I have a large 180g and can't remove the remaining fish (algae blenny, engineer goby, pacific wrasse).

I want to have an ICH free system. I have read and understand the cycle of ICH---and that you need a fish free system ......but I can't get the fish out.

So, I am looking at alternates...how would Ozone work in this situation......would it kill the ICH cycle even though I may have 3 fish left in the tank.

To use O3 for parasites and other hard to kill pathogens, you would have to use so much to kill them that you would kill everything else of course.
If your fish have ICH no usage of O3 or UV is going to cure them.
However, a properly sized UV sterilizer does a decent job of killing pathogens etc. in you water column.
Providing they are water borne and not on the rock of course.

IMHO, and from 2 years use,go with ozone!

"For aquarists that don't manage nutrient export as well for whatever reason (do not want to do large water changes, very heavy bioload, etc), ozone is often a useful tool to improve water quality. This is a prinipal reason why public aquaria use it (heavy bioloads on displays and they cannot afford to do large water changes)."

and . . .

"ozone for most folks (home and public aquaria).... UV only for bare-bottomed commercial installations (its the only place they can be of any good use/value IMO due to their limitations of efficacy based on strict installation and water pre-treatment requirements which I have outlined in detailin this forum/the archives if anyone cares to delve further) "

What you are quoting states that it helps to remove nutrients.
I agree with it 100%, I use ozone for that myself.

But your excerpt says nothing about parasite/pathogen control.

thinking it over, ozone may help with the floating stage of ich but not when they are on the fish or hatching in the substrate....

ozone in itself is a good idea, if it can only be done simply and cheaply without an air dryer, reactor, controller, carbon, etc.......

i just can't get the last fish out of the tank.....

 

[SeanT]

Ozone will do nothing for the floating stage...unless it floats into your skimmer.
Ozone has a life of approximately 30 seconds and is effective only where introduced.
The choice is yours, O3 will help clarify your water and skim more effectively but it will not control ICH.

my quotes were from 'the genius' . . . if one would like to read all of his posts and/or do a thorough search on 'ozone', i beleive he or she would find support for both nutrient control/export and disease/nusience algae etc...mitigation

Hi,
If the fish are feeding you can try medicated feeds.

Genius? Hardly.
You are the one who is quoting Calfo so quote something of substance that states ozone is useful, and more useful, than UV.
That is your source so substatiate it.

The aquaculture books I have read state that you would need a contact time of well over a minute (3-30 min) to kill most pathogens.
