Any help as to why these are dying??

What are you using to test salinity?

 

[Brancho]

Stability.

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

Sorry I don't understand. I don't know why it fluctuate I'm still learning. I do dose mg and AK. Test the new water or old? I only test new water for salinity

To mentioned and define stable .

my Alk has been 7.5 dkh +- 0.25
Salinity is always 1.026
Cal 425
Mag 1350
Temp , 79°
nitrates 2.5-5 ppm

I can drop a raw shrimp in and if it’s not eaten I don’t need to worry about ammonia

What is the tank size?

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

That looks like a pulsing Xenia and usually those are very forgiving but also like a canary in the coalmine if something has them off. They'll start to curl like that and shrink up. Good news is they will come back when things get back into line.

I see that you report Nitrate and Phophate in okay levels. What was the actual test that you used? Salifert? API? Red Sea? Something else? Asking because I've seen different test entirely mis-lead me as to what was wrong especially for Phosphate and Nitrate. Based on what you mention, feeding roids on a 7 month old tank, I would not be surprised if your phosphate was significantly higher than that and the cause of your issues.

You
Said stable .
but there are fluctuations . They’re asking if you test the new water before water changes

What is the tank size?

130 gal

 

[Tamberav]

Bring your salinity up and this will help bring your Mg up.

1.026 as others said. Just top off evaporation with salt water instead of freshwater till it hits 1.026

 

[Rmckoy]

Ah I meant mg?

 

[jabberwock]

Plenty big. Bigger tanks take longer to reach stability but maintain it better.

I use api for ammonia and nitrate. Salifert for ca mg and ak

Ah yes I thought they were stable lol

It’s not too often a 7 month old tank Is stable to what’s required to keep sps healthy

So any tips or just let it runs its course ans keep maintaining it

Well my vote would be to take a second look at the Nitrate and Phosphate. Roids especially will raise Phosphate. This doesn't happen quickly usually in a new tank because the rockscape initially acts as a phosphate sink though eventually it'll saturate and the phsophate increases in the water column.
The Red Sea test is actually very good and reliable. Based on what you've said I think it would be worth investing in to get a second opinion so to speak.

Ok, just checking if maybe something was out of calibration. I personally like the BRS solution.

Sorry, I didn't see how old the tank was, but do now. I hope it works out for you.

 

[Brancho]

This is my phosphate maybe .2? Should I reduce it?

 

[Screwgunner]

Yes . Your goal is .05 for phosphates. I know you are new. But you need to look up vodka dosing. It will keep your nutrients down and you will not have to change your water as much.
