Any help as to why these are dying??

[Brancho]

Hi still new to this and my tank is 7 months old. Paramaeters are stable. Salinity 1.023 ca 440 mg 1180 AK 8.9 o ammonia 0 nitrite 10ppm nitrate 8 ph. I feed once a week roids plus some plankton and aqua elixir. Change water once a week. I did have an ammonia spoke last week due to a clam dying while o was away for 4 days. Any help appreciated pics attached. All other corals seem fine

Mg and salinity are low. Also, how old is the tank?

Mg and salinity are low. Also, how old is the tank?

As mentioned above , tank is only 7 months old .
My thought …. Between low salinity ( I would question the accuracy of the Alk test .
A ammonia spike from a dead clam I would only hope a mature system would be able
To process the ammonia

7 months I can up the salinity 1.024 mg fluctuate from 1150 to 1250 always find when I change water it goes down

7 months clear as day. Ammonia is a killer I did not see a phosphate reading. Mag 1400 salinity 2.05 2.06 rual of thumb is one year for sps and very stable. No big swings in alkalinity and phosphates.

Salinity needs to be 1.026
When weekly water changes . Mag value should be restored to normal as its intake
Should be minimal .

this system is far from being stable .

It took 2 days to process and a water change. AK always is always 8 to 9

Whats normal?

Why are you only bringing salinity up to 1.024 ?
Corals , especially sps will not be happy with. Those parameters

Stability.

Why does it fluctuate?
How.... Do you test the water before changing it? SG that is.

NSW …
1.026 ( 35ppt )

Phosphate is stable .1

 

[Screwgunner]

Move every thing up slow do not rush it. You will only make it worse.

Agreed

What was the ammonia level?

 

[Dburr1014]

Phosphate is stable .1

This is only 1 part of the equation

 

[Screwgunner]

Opps 1.026 sorry

Ah I meant mg?

 

[Screwgunner]

1350 1400

I keep mine a little high 1500 helps with algea alittle. Coral doesn't seem to mind.
