Help Magnesio is went to heaven!

[AbrahamS]

Hey guys, I hope I can help my Salifert test expired without realizing it, I realized when I started my acros give RTN check all possible parameters and could not find a solution.

I visit a friend to check with their test. effectively Salifert test of Magnecio was wrong, I have the magnecio in 1910.

I have understood that after 1600 the magnesio not precipitated. So if i do a WC did not help, would be like if i add more

Whay i could do this level of magnesio its killing my acros 1 by 1 i lost 1, also 1 monti digitata is sick to and the half of my hammer die.

First get a new test kit and check the Mg today.
Water changes with salt mix rich in Mg, if needed.
Every other day test, and gradually add Mg to the system, if needed.
Can't do much more than that.

Thx for the answer Gradis.

Water change would help? My salt has Ca 430 Mg 1480 and dkh in 9.

So my question is ¿how much do i need to change 50%? My tank has 175 Gal or do the wather changes periodically whit low % of water change?

 

[A. Grandis]

No problem!
Yep, do a 10% every 3 days, at most. Things will get better that way.
Don't forget to check often, 24 hours after each water change.
When parameters get back to normal you'll need figure out how to maintain them, testing and adjusting…

I have had magnesium up to 1800 for a period of three weeks (Tech M treatment for bryopsis) with no issues in a 300 gallon SPS tank. I would look for a different reason you are losing your SPS. I don't think elevated magnesium would do it.

Agreed. The only issue I've read about and witnessed myself with high magnesium levels was turbo snails getting a "drunk" feeling and falling off the glass and rocks, but it doesn't kill them. Once the magnesium dropped below 1,400 all was well.

 

[AbrahamS]

Really? well i dont know what else can i check it i alrdy check

Ca 430 Mg 1910 dkh 8.5 P04 0 N03 0 N02 0 Ph 8.2 Amo .005

Maybe the low nutrients but what can i do ? they have like 5 monts in that levels and they only have 1 weak whit the rtn and not all my sps.......

Well, perhaps you didn't have RTN in your system to start with.
We really don't know if the Mg would be the main reason, but it isn't good to keep high Mg in any reef tank anyways. Otherwise it would be recommended, right?
First things first"¦

Deal with the Mg and see how it goes"¦

Would you think of anything else for he to look for in regards to his RTN problem?

Too high or too low Mg will affect Turbo snails and other species as well.
They do fall on their backs and stay alive for a while, but I never had that happen with high Mg, only lower than normal.

We'll see what others would recommend to look for in a tank with RTN"¦
I'm excited to learn more...

[AbrahamS]

I'm excited to... I think Mg like The other levels of the ionic balance they hace a maxium to reach after that its dangerous to keep that levels.
Im not an expert whit sps and i dont know what else can regard rtn con the corals

I've had as high as 2200 magnesium in tanks with no ill effects in a mixed reef with plenty of healthy SPS. Something else is likely at play here... However, if you really want to drop it and think that's the culrpit, I'd suggest a couple larger water changes. I can do 50% water changes without any real stress, you just have to let it mix well, make sure you're not making any big jumps with alakalinity, and that you're matching the salinity.

For how long you had the MG at that levels? if something else is wrong what could you say about it? its hard to know but.... people whit more experience should know what cause the rtn....

 

[A. Grandis]

Hummm. It would be great if the more experienced Acropora reefers could give their inside here! This is a great subject!

There are many things that could trigger RTN and we guess it would be most of the time probably related to stress, dropping the colonies' immune system. First of all the RTN pathogen needs to be present in the system, so quarantine is what really will keep it out! High Mg would provoke an unusual/unatural water chemistry instability, at least while it's happening, and could stress some corals, of course. The stress would contribute to the RTN. Higher Mg level wouldn't be the responsible, if the pathogen wasn't introduced in the first place. Quarantine is what will save your corals from that tragedy. The worse part is that RTN can stay "dormant" for a while, and the hard decision now is to decide the best time range to observe the new additions in a separated tank.

You recommended three water changes with a salt mix rich in magnesium and adding mag to the tank for an elevated magnesium level? I am not quite understanding that? Perhaps you thought his magnesium level was low?

Well, perhaps you didn't have RTN in your system to start with.

Would you think of anything else for he to look for in regards to his RTN problem?

Grandis.

No, it is not necessarily good, but I'd rather have an elevated magnesium level than almost any other.

Look to any of the hundreds of accounts of Tech M treatment for bryopsis that have maintained 1800-2000 levels of mag in their systems for weeks on end, and you will find no reports of SPS RTN as a result of it.

The cause of RTN in an SPS system could be from many causes. OP has not posted any of his tank particulars. Pick one, any is just as likely as the other. In threads like these, the participants are blind with no system particulars given by the OP.

My advice to OP about his high magnesium level is to quit dosing magnesium if he is doing that. Test every other day, and let the mag level drop through use by the tank inhabitants.

Some Reefers look for an imbalance in their water chemistry to explain RTN/STN, when it is simply a matter of water flow, for example. SPS reefs when young have numerous small frags which don't require a ton of flow, but as these colonies grow and increase in size, they start to block and change the entire pattern of water movement in their tank. Mature colonies have areas that get more flow than others. I had STN in one of my earlier SPS tanks at several colony bases, and it was a simple matter of switching out the in-tank pumps for more powerful ones that solved the issue. My tank was fine with lower flow with a bunch of small sticks in the tank, but mature colonies need more flow to bring in food, O2/remove waste to the entire colony.

Diagnosing the OP's problem without system particulars is like looking for a needle in a haystack.

Thanks for the explanation..... what else do you need to know for try to give an diagnosing?

System? watter flow? lighting?

I still can´t believe how overlooking a high magnesium and wait for it to drop. The last thing that i know the base of reefs are simple, lighting and the ionic balance is the most important of a sps tank beside a good flow.

does it work if i give you the full info of my tank?

Size 63"x25"x25" whit sump gives a total of 165Gall of water
Ligthing 98 3W leds Reef breeders 40 20°k whites 45 RB and 10 Violet 3 Cyan
Filtration Skimmer EuroReef 250 -Biopellet and phosphate reactors.
abouth 90lbs of live rock
Dosing Pump Bubble Magus wich adds Ca Mg and dkh daily ESV products
water flow is running on 2 Jebao Wp-40 working at 100% of his capacity.

i do weekly watter changes of 16 gall

I would blame driving nutrient levels too low via GFO and biopellets long before an elevated magnesium level. Just one of many things to consider. Pictures are often helpful if you have any. Also, how long have you had the WP 40's and did you notice issues starting when they were added?

What makes you think that all RTN is directly attributable to a pathogen? RTN is generally linked to a variety of stressful events and conditions and no pathogen needs to be present for it to happen. In fact, RTN and STN are made up hobby term for the most part, tissue necrosis in general is a stress related malady that may have some links to a disease or pathogen, but by no means do that pathogen have to be present for it to occur.

Agree whit RTN are atributable only to a pathogen. A simple little change in the tank like watter light temperature etc.. Can stress the acros and start the problem... Let me know if im incorrect....

I dont think so about jebaos because i have them since i set the tank

This is my tank like 1month ago it looks little bad the picture cuz was taken whit a cellphone sorry abouth that ....

 

[AbrahamS]

This is how it looks the pocilleopora with RTN i will add some acros.... They are frags i dont have colonies jet......
