Help! All my Coral are dying! High Alk and low Mg and Ca

[miloreif]

Title says it all. I’ll list my parameters but for the past week I’ve performed 30% water changes to lower Alk and I’ve been dosing Mg and Ca everyday slowly to raise them. Are these parameters related? It seems when I’ve added Mg, it raised the Alk from 13.0 to 14.2 dKH.

All my fish seem fine but my corals are dying. I lost a brand new torch and all my other corals are showing signs. I also dosed Mg this morning that should’ve raised it by 100pm but I saw no difference. Are my tests flawed? I’m using Sailfert for Mg and Alk. And I’m using API for Calcium.

Ammonia: 0
Nitrite: 0
Nitrate: 10ppm
pH: 8.1
Salinity: 1.026
Calcium: 400 (it was 360 last week)
Alkalinity: 14.1dKH (it was 13.0 before I started dozing Mg and Ca)
Magnesium: 1200 (it was 1100 last week)
Phosphate: 0.05

Also my water is super cloudy now.
I’m dosing with SeaChem Reef Advantage Magnesium and Reef Seachem Calcium

stop dosing let things settle down !

I don't trust API, used it at the tank cycling stage but recommend upgrading once tank has cycled. What kind of salt do you use?

Stop dosing things. Water changes should be sufficient. The cloudiness is likely precipitation

 

[CallMeLloyd]

I agree with the others, looks like if you stop dosing and just do normal 10% weekly/bi-weekly water changes the alk should come down, cal & mag should go up. Unless for some reason you are using a salt with lower values. Make sure your salinity is correct on newly mixed salt water. Hope this solves your issue.

yes they are connected. As suggested above id stop dosing and do wc.

I think you paramters are fine, although alk is high. Cloudy water? how old is the tank? thats weird. Increase the surface aggitation and run a skimmer
