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. :cool:
