[mcmunn93]

Hi my tabk is now 8 months old and Ive got red plate montipora and it's just starting to fade so I tested again
Calcium is high 600
Alk is high too 8.6
Mag is 1470
Reason for this fault is I've just bought a new dosing pump and trying to adjust so I've stopped dosing calcium and alk for now

But because there high what can I do and whats gunna happen to my montipora

Thank you any advice please

What is your no3 and po4?

Monti's are hardy and as long as you keep your water stable (after correcting any issues) it will make a comeback.

Agreed. By the looks of the monti I would say the alk spike is the issue. What do you normally keep it at? 8.6 isn't terribly high but it you kept it lower and it raised quickly the spike can cause issues. Once things are stabilized I would bet it will be ok.

My no3 and po4 is 0

So how should I lower my calcium because that's really high

My alk was at 7.0

If ALK spiked in a ULNS it will cause issues.
If no3 and po4 are present it will have a less dramatic influence on the monti

My alk was at 7.0

I would let it drop naturally
No3 around 2ppm and po4 around .014 will help from alkalinity swings

 

[mcmunn93]

Ok thank you would a water change help or no

 

[mcmunn93]

Would you say my montipora is in the right place

Looks good from the picture

I would let it fall naturally. The high calcium isn't too much of a concern. Dramatically dropping either cal or alk (especially alk) is going to do more harm than good in my opinion.

Ok so just keeping testing regulary but keep dosing magnesium cause my magnesium is perfect

Magnesium uptake is minimal compared to ALK
If it is in range then I would not add any more

 

[mcmunn93]

Should i stop my dosing pump for magnesium

Well... are you growing a bunch of mangroves ?
Mag is not consumed near the rate of cal and ALK.
@Randy Holmes-Farley knows a lot on this

Yes without a doubt.

What are you dosing, 2 part? Let's say it's brs 2 part, you only need to dose magnesium after you finish full gallon of alk/ca or as needed.

But what if this person is growing mangroves??

 

[xmas_one]

I dose BRS two part and I will only test for Magnesium once a month. It seems like I'll only need to dose Magnesium once every two months.

Are you employing the triton method?
You have a pump for mag?

 

[mcmunn93]

No I'm not growing mangroves
Ok I'll stop dosing magnesium
