It is good to hear that the RTN cycle is in remission.
Here is the million dollar question. Did the progression of RTN stop because?
- Solely based on the addition of O3, the use of excessive carbon or UV?
- Combination of those 3 things?
- The addition of the antibiotics and prime or either one or the other?
- The combination of everything that you have done or a couple of the things in tandem?
- Because the disease has naturally reached its conclusion
- Because of whatever caused it to start in the beginning has been fixed inadvertently.
- A combination or none of what you have done?
Unfortunately because you did so much we will never know. Unless of course you were prepared to begin the experiment all over again and leave out certain steps.
Ok, I think the reason RTN/STN did reduce is based on a biological battle going on in the tank.
I could stop the STN for a day or two then it popped up again slightly.
So with the coincidental help from Kryzstof Tryc which helped me in the past concerning Biopellets we were discussing the previous bio pellets we both used that were discontinued and he made me aware of the fact the pellets are now been made under a different name and shape (Long story, the company split up). So I got these particular pellets out of Europe and started using them yesterday.
In the past they seems to have a very very positive effect on the bacterial biology and coral health!
One thing I noticed overnight already since yesterday with nothing else changing, is that the STN came to a stop again and the water column is much cleaner now! The haze is almost gone in the water indicating less bacteria count in the water. I felt that in the last weeks and months that the haze in the water had a very negative effect on the tank hence I was looking for a better way to deal with nutrient reduction without high bacterial count in the water which seemed to contribute to health and colors in the tank. But while the tank was developing and growing, the bioload became more since I started the tank and after a while the haze in the water started to appear at some point again after I could not replenish the pellets anymore.
Seeing this change overnight by using the pellets, already supports this theory once again.
So I use UV, Ozone, Activated carbon and now the pellets. Also supplement daily 20ml of Eco-Balance per 100G tank water. Just to support the bacteria strain diversity.
So in general, the bacterial count in the water indicates good and bad guys, it's important in my opinion to find the right setup and method to run the tank with pristine water. Yellow greenish water is not that bad, as long it's crisp, means barely any bacteria in the water column.
I always supported the fact that too much carbohydrates (depending on the type of carbohydrates) that fuel the good bacteria will may also fuel the pathogenic bacteria.
Likely not, but less bioload now due to losses ;-)
See above.
Unfortunately this thread has created way more questions than it has answered.
Just wondering out loud again:
- Is O3 effective at reducing the mobile pathogen(s)?
Actually not, it breaks down larger organics into smaller organics and makes them available for more bacteria strains, hence increased strains of bacteria which may tackle the decomposition of organics more effective, and also reduces the toxins and increases light penetrations which also helps in certain cases the metabolism and repair function of corals and it's tissue.
- Has anyone had RTN on multiple coral colonies while employing O3?
Me
- If O3 is effective at reducing the mobile pathogen(s) would a Sochting Oxydator help?
O3 does not kill pathogens and apparently deactivates some bacteria.
UV helps but can deactivate as well as kill which depends on the UV light and reaction time.

H2O2 also kills bacteria - so I don't think it helps decide what is causing RTN. It will also help 'clean away' dead tissue.
Very true!!! I saw it under the microscope. The cleanup works very good if you lay corals in tankwater for an hour or two after the dip.
