Can RTN Cause???

Tank2379 · Mar 30, 2016

Hi All,

I was just sitting here wondering about RTN. I have been experiencing this in my DT lately with a couple colonies. I have been doing water changes and stop all dosing like Aminos . I hate when things work to well. Water parameters are in check- Alk 8 Cal 440 Mag 1400 Nitrates 0.2ppm, PHOS 0.2 ppm. Anyhow Can RTN in one SPS effect another SPS to RTN? Any experience with it let me know.

Thanks

I hear you brother. If there is one thing that I wish we could figure out it would be RTN and STN. Over the years I have lost thousands and thousands of dollars of corals due to this issue. I am having issues in my current tank that is driving me crazy. I have been keeping Acro's since the early 90's and it still isn't figured out yet. Wish we could find an answer and a treatment that would stop it .

Thanks for responding, yeah it's driving me crazy as to why does this continue to happen especially to a lot of seasoned reefers. I know Sanjay was experiencing the same issues and couldn't explain the reasons behind it? ( Unless I missed that part). I could only think of Chemical warfare between Acros since some come from different areas of the ocean. I am not sure but that could be one reason.

I lost corals in the past too and recently had a few to STN but they got back to normal. I tend to either do nothing or do something very slowly. My take is that the corals are already stressed, and doing large water changes or decreasing organics really fast with a lot of GAC would stress them even more. Unless I have a very clear reason for the RTN or STN, I will reduce the light a little, and add GAC with very low flow (1 x tank volume / day). Is that a proven methodology? No. But in my experience it has helping more than what I have done in the past.

One day I'll have a 400G tank like you
