**Help needed please**

[Ry1]

Hi guys, Firstly thank you for taking your time to help.

My Zoas and my Duncan have not been showing now for over 2 week. I really don’t no what the issue could be, can anyone shed some light.

Amm-0
Nitrite-0.1
Nitrate-5
Phos-0.1
Cal-440
Mag-1240
Alk-7
PH-8.0
Salinity-1.025

Nitrite should be zero; Mg is looking low; double check the salinity reading with a properly calibrated testing method (as applicable). Lighting?
I would also look into the option of dosing phyto and aminos (depending on system to help with coral nutrition). A healthy bacteria population would also help, but that is hard for the average aquarist to determine. I dose small amounts of bacteria for my system twice weekly.

So many factors and even more difficult to pinpoint due so many system variations amongst systems.

Just all suggestions to help with troubleshooting. Hope the issue is found.

Tell us how old the tank is.

Basics about lighting lighting intensity photoperiod....

What's your source water....etc.

What are you dosing?

So the tank is 4 month old. I use an Ai prime 16hd for the tank which is 100L with built in sump.
I use NSW which i buy from the LFS(Very good reputation)

I am dosing AB+ once a day 4ml and Reef roids once a week.

Depending on your location, the natural salt water may become an issue. We had phosphates coming in at .5

to me btw it looks like the Favia family coral or acans? you have in the photo also look stressed. It's probably a water quality situation.

Can we get photos of your other corals?

I'd recommend switching from NSW to Store Made first and see how that goes, then try maybe making your own if it doesn't improve.

Otherwise find another store.

The tank is young, and while the water quality "Raved" by others might be great in their more established tanks. It could be causing the problems in yours. NSW can come with all kinds of nutrients, your system might not be totally equipped to handle it. Thus adding more water and doing more water changes to address the problem is probably stressing them out???

All just probable depending on the hypothetical that the water is the problem.

4 months is a very young tank in my opinion. I am thinking there is not a very well established bacteria population yet, especially since there was a slight reading on nitrites. Just my thoughts so far.

These both require same minimals:
Alk at at least 8
moderate light and water flow
RO water instead of Tap water from sink

What is ammonia and nitrate level ?
What is tank temperature?

Try:
moving white intensity to 20%
Blue to 80%
UV to 77%
red to 5%
Green to 4%

Add a little lugols iodine to the water
Blow gentle burst across both pieces with a turkey baster and aim flow towards, , , NOT AT . . . . these frags

It's a new tank, so there's is some maturing left to do bacterial strain wise. NSW will help, but some live Rock from the ocean will help more.

What are you using for top off water?

Aside from the newness of the tank and your water parameters, what's your photoperiod, light intensity settings?

Duncan's can be finicky.

 

[terraincognita]

I am dosing AB+ once a day 4ml and Reef roids once a week.

Are you feeding fish as well on top of this amount of dosing?

If you are, you have a nano tank, and that is a LOT of nutrients. I'd recommend dropping those doses for sure.

Its shop bought nsw.

I use RO water for top up.

and these are the settings that run most of the day. I run my lights from 8am- 8pm

Your zoanthid rock looks like is covered with a film of something green or brown.

If it is, you might take it out of the tank and swish it off in another container of saltwater, then put it back in.

Yes i am feeding half a cube of frozen a day

Ok thanks i will try this

IMO too much nutrients for sure, unless you have some crazy awesome filtration. Not sure what you have running sump wise etc. Might be fine with super high filtration.

They make most of these for systems 100G+

Nano's dont necessarily scale down the same IMO.

i.e. I'd safely say if you dosed 75% of a 200G dose in a 150G tank you'd be 100% fine.

I dont think dosing 10% in a 20G is quite the same if that makes sense. I'd say 5% would be safer.

 

[brmreefer]

If it were my system here is what I would do after getting additional info about the system.

1. Stop reef roid dosing regimen. This can be started back later.
2. Greatly reduce amino dosage until system gets older.
3. Look into dosing some bacteria for increased strain variations.
4. Give it time to get established.
5. Try and keep corals alive for now and hold off on buying additional ones until later down the road.
6. Exercise patience and let the system slowly grow. Nano systems can have drastic changes in parameters that can shock livestock if not kept up with.

Wishing the system the best and "Stability" will be key. Take care
