ICP test/ hanna calcium checker/ trace elements

[Łukasz]

I get my ICP tests back and I discover that some of trace elements are undetectable. I use red sea pro salt and I thought that I have them a lot so I don't need to dose but after check of the test I ordered red sea abcd.
What was the biggest suprise is my calcium on ICP test. I have hanna checkers and I wrote my perimeters on my previous conversation I measure calcium around 500 on my hanna checker but ICP test show that my calcium is 411 so is a very big difference. I also ordered calcium test from red sea.

My question is: If I dont have enough trace elements in my aquarium is possible that corals are bleach (SPS), hammer coral loosing some polips on one head and my zoas - not all- are close?

My perimeters from the date when I send the ICP test:

red sea pro salt: 34,8
Temp: 25.6
pH: 8.2
Nitrate: 24.9 slowly going down from 29
Phosphate: 0.113 going down from 0.34
Alkalinity: 10.3 this stay around that number through many moths (9.8-10.3)
Calcium: 473 go down from 520 which was high like this couple months
Magnesium: 1560 this go up from 1420 which was on that level many months

I dose:
red sea alkalinity 6ml in noon
red sea NOPOX 7.5ml at 9am
I also use rowaphos in small amount, 5-6 teaspoon

Aquarium with sump have around 360l of water.

Just an FYI, come of those "setpoints" are crazily narrow windows that have no data justifying them.

That said, you may benefit from a trace element supplement such as Tropic marin A and K. Only way to really know is try one and see if anything benefits.

Both calcium values are fine, but it's worth noting that the Hanna calcium checker is among their worst (IMO), and is a poor design (IMO) and often very frustrating to users.

I bought already red sea ABCD and I will check if that will help a little bit.
Do you know if hammer coral can loose polips because of the very low trace elements or this can be a bacteria infection?

I’ve not heard of losing polyps as a response to depleted trace elements, but if there really was none the coral would eventually die.
