what makes my barium cross the threshold

[Chippinguyen]

Hello friends. I just received the results of my ICP test, was surprised with the barium level above the allowable limit. What do you think is the cause? coral feet show signs of bleaching
I am using: ZEOvit, Activated Charcoal, ZEObak, ZEOfood plus, ZEOstart, Sponge Power, Pohl's Xtra Special, Coral Vitalizer, Amino Acid Concentrate, Acro Glow, Coral Snow, Bio-Mate

I have no good experience on this issue, and I cannot tell you whether the element barium has unhealthy effects on corals. At present, I can only get some preliminary ideas from the coral appearance, rock materials and biology in the picture, but it is not very clear. You can fill in the basic information about your tank and you will learn more

From the signs shown by the corals in the picture (bottom TN), let us check the salinity level (precision salinity meter, it is correct), and obtain the cross-comparison of different test kits (KH, Ca, K+). Of course the Mg level is also Need to be maintained at the correct level (ZeoVit system: Kh6.5-7.5 Ca400-420 Mg1250-1300 K+~380g)

It is unclear whether the zeolite material and KZ activated carbon are used and the quantity/flow rate used

These two components have affected many levels, especially the current coral health (coral bottom) has been impaired

Thank you for replying to the basic message, but I am sorry, I am not very clear, my language skills are limited.

No, the coral doesn't look hungry

What I want to say in #2

What kind of salinity meter is used?

What is The net water volume?

Generally, if magnesium is not added, it is usually not at 1400 level, and the basic water parameters are high. Let's start with the "salinity correct" check, and use different test packages to cross check (KH-CA and K+)，Get the correct level and be as stable as possible (quite important)

The volume of the net water volume is related to the zeolite material and the quantity and flow rate of KZ carbon

Thanks. I just edited my post

First thing I would recommend is to get a new Ca test kit as yours seem to be not accurate. Please also cross check the KH with a different test kit to make sure your test is accurate.

Otherwise I can not see anything special however the system is just 2 month old and the biology is still improving which can take some additional time. Are the rocks you have used live rock from another system or are those dry rocks which are massive and compact instead of porous ?

I have seen some systems with a elevated barium level over the years but the elevated levels seem not to have a impact to the corals.

Here are two example threads:

https://forum.zeovit.com/forum/gener...by-high-barium

https://forum.zeovit.com/forum/gener...-zeovit-barium

I would not do anything special, just some smaller changes to your dosing regimen:

ZeoBac – 10 drops 2 – 3 x weekly
ZeoStart – 1 ml 2 x daily
ZeoFood – 10 drops 2 x weekly
SpongePower – 10 drops 3 x weekly
BioMate – 20 drops 2 x weekly
XTra – 5 ml 1 x weekly
CoralVitalizer – 10 drops 2 x weekly
AcroGlow – 5 drps 2 x weekly

The ZeoVit reactor flow is to low also, should be ~ 1000 liters per hour however at the moment while the corals show basal TN I would not change it, you can do this later once the corals have recovered.

Do a weekly water change of 10 – 15%

What type of salinity meter to use? refractometer

What is the actual mass of water? about 800 liters

I have never supplemented with Mg. but still very high. my target is Mg 1300

Thank you G. for your help, as #8 said. Start with the basic water parameters to ensure that the level is correct, biologically young and dry rock materials may be a problem (unsure)

I reduced the flow from 600l/h to 300l/h when I saw my No3 and po4 down to 0. Will low No3 and Po4 affect the health and growth of my corals?

[Chippinguyen]

I used this filter ceramic from an old system

[jacky]

The URL of the link in #8. I don’t think it’s too much to worry about, it shouldn’t have a negative impact on corals, and this element does not seem to be stable. In addition, that’s why I personally don’t use this material as a biological filter.

The first priority is to stop the coral and continue TN

Low NO3 and PO4 are definitely the best for coral health and growth. The reactor flow rate is from high to low, which will affect certain aspects, such as the increase in nutrient levels. Due to the current TN of Coral plus changing the reactor flow rate, it is recommended not to change too much (in addition to the suggestion of #8, it also allows us to confirm the current phosphate level and the current actual reactor flow rate) also let us implement weekly water changes 10%

As you described, you never added magnesium. Basically, for all salt mixtures on the market, the value will not be 1400 at the correct salinity level, otherwise the test package is abnormal or the test is wrong.

Do you use purified water (TDS=0) as the water used?

[NZ-Nick]

Hi ya all.

this barium is an interesting one.

Just mixed up some redsea calcium foundation.
it contains Ca, Sr, Ba.

googling around
faunamarine-barium - they state active carbon, cements, and foods as source ?!?!

removal - water changes - removal active carbon and aluminium-based phosphate adsorbers.

they mention high barium and low iodine - tissue turning gray ?!?

NickB
