UPDATED: Any Help is appreciated

[Lampshade]

There's an interesting article about RTN i found awhile ago. RTN is pretty much like looking at a dead guy and saying "he died fast". How did he die? that's totally different. Corals get sicks much the same as people, lots of different diseases caused by many different things. We all have slightly different parameters in water, dosing with different chemicals etc, so saying one thing causes it doesn't seem to be effective. There's very few things known about RTN, but we do know that stressed corals are more likely to get affected. Corals can regrow, even RTN'd corals, so according to this the best thing for RTN corals is high flow, stable parameters and fragging if possible.

Ineteresting article though, i'm sure some of you have found it:

Update:

It has been over a month since my last update. Well I am much happier, things are not perfect, but doing very well.

In regards to the zoas: The hippo Tang is not eating anymore, so I have lots of them left and they are happy. I am contributing the fact that maybe the other zoa colonies are toxic, and Dori doesn't like that. The colonies she destroyed, well maybe they were NOT toxic and a tasty meal. So on that note, zoa issues are done with for now.

SPS: I can say the sps are doing much better. Most of them are showing great signs of growth. Lots of it... and the RTN has basically stopped or is so slow I am not really noticing it. Some corals may be far too gone, but overall I am seeing great results now.

In regards to the coral, I have taken the approach given to me by others. The fact of going more basic!!! So I had changed the following:

- Removed Zeovit reactor with zeolites
- Removed ZeoBac dosing
- Dosing coral snow once a week, it was daily
- Dosing coral vitalizer twice a week, it was daily
- Dosing zeo amino acids daily but at much smaller amount
- Removed dosing of CoralFood7 for now, with fish poop, etc. coral seems to be responding well
- Added dosing of ZeoStart2 daily at lower than recommended daily dosage
- Added the second skimmer
- Doubled weekly water change to 16G per week, using Reefers Best Salt
- With the increased water changes, I have NOT done any dosing of Ca, Mg, St or trace elements. I only do a small dose a day for ALK, but otherwise no more dosing elements.

I am still using the NP BioPellets with carbon.

Things I am noticing besides the improvements in coral are:

- All hoses that Pellets ran through had a film on the inside of them, this is now completely gone and all plumbing and hoses are very clean. Same goes for the NP BioPellets reactors, very clean inside.
- Sump even is very clean, noticable difference in water clarity, walls, etc. I never clean the sump... It looks like I cleaned it, but I haven't
- water clarity is staying consistent, not having issues of losing this quality and then it comes back. It is now always clean.
- don't need to clean glass as often, everything looks very prestine.

So I have to say, going much more basic seems to be working. Plus it is saving me money. Thanks for the input from the others, you know who you are. I hope things keep going well, and I keep seeing the coral revitalize. As I said some may be far too gone, but oh well, time will tell.

I hope others reading this can gain from my mistakes... I hope this can help others.

Just another update.

Well I can say the tank is on the road to recovery, and corals keep getting better.

Since the last update I made a couple other changes:

- Firstly I removed the deep sand bed (DSB), and just have live rock in the refuge area. It was quite nasty when I removed it, so most likely a big nitrate maker and poison to the tank.

- Also last week I tried something... I use a Mag18 return pump running full blast, so water drains, goes through the refuge/sump and back into the display rather quickly. I reduced flow to about 20-30% of what the return pump does, using the return plumbing valves, thus really slowing down flow into the overflows and then to the sump to a much slower flow, not a gush anymore. Well it seems that the 2 skimmers, LR, Pellets in the sump have more contact time on that water, and therefore the returning water in the display tank is much cleaner. things I notice are other corals that were not showing good results/healing are now, any foam in the bubbletraps that was forming isn't now, and overall tank quality/water quality is even better.

Yippeeeee!!!! keep the good stuff coming. Hopefully soon, I will be hitting everyone up for new corals to replace my losses.

Good to hear man good luck I hope the trend continues.
