Corals and anemones not happy!!!

[ReeferTang44]

These guys aren’t doing great

Three polyps have been closed for a while

Not sure quite what is going on because meanwhile my other corals are thriving.

Phosphate of .5-.7ppm.
Is that a typo, do you mean 0.05-0.07ppm?
If not, there be a contributor.

In addition Alk on the north end of high, but if stable ok, salinity is too high and may account for your elevated parameters

How should I lower salinity stably

 

[RabidDragon]

if the salinity is actually 1.027 then I agree with Uncle99... not sure with the handwriting...

 

[ReeferTang44]

Yes 27 and yes to 0.05-0.07

You could use a bit more calcium (+50ppm). I'm not sure I understand the alkalinity number; what is it in dKH?

 

[ReeferTang44]

Yes dkh

Dropping salinity can be done a lot more safely In a rapid session than raising them. A water change with a new water of like 1.022 should be good

mag-po4 and salinity elevated.
You want mag 1350 range......... salinity at 1.025 and phos at about .1
If youre feeding reef roids often or overfeeding - reason for po4 and salinity you can do a 10 gallon water change and replace with ro water at same temperature as display tank and mag- do not add ay until it drops

How should I lower salinity stably

Just add RODI until you get to 1.025
You can automatically maintain that with an ATO, IMM, a critical piece of equipment which maintains salinity stable.

Wait till the mag gets lower then add and feed less along with adjusting salinity

 

[ReeferTang44]

Is that what I should do

Yes
