ph 8.3
nitrate 0-10 looks more the 0 but i give it a lil room just in case im missing reading it
phos 0
cal 450
mag 1000
salt 1.025
temp 78-81

plz help

What is the alk?

 

[pimp2daizzo]

9 dkh

Your MG is only 1000? Recommended range is between 1250-1400. Try to remedy that.

Mg is low also is the part of the bridnest in question a part at the bottom that is shaded by the branches?

 

[pimp2daizzo]

i tested my mag its now at 1126

and its pretty much all over the nest besides the tips from what i can tell

 

[pimp2daizzo]

my total alk is now at 4ppm and my borate alk is 2ppm n my carbonate alk is at 2ppm

ghost where you from in ga>?

Camden County.

Your alk is only at 4 now? Are you sure about that?

If that is the case, that from yesterday to today you went from 9 down to 4 that is a problem (and honestly I don't know the difference in all the alks you listed).

im from gwinnett

lol ya it the seachem test kit and it says to subtract the borate alk from the tot alk to get the carbonate alk, but i don't rly get it the kit says its good and when i test with my api it say 9 dkh

Raise your mg and a change in bulbs can shock coral a little bit, especially if you change brands, spectrum, or wattage

where should my mg be? and the bird nest kinda started before i change the bulb

 

[pimp2daizzo]

anyone think it could be the skimmer i just put on a new one

I 100% doubt it has anything to do with your skimmer...

Receding from the base can also be a sign of a flow issue. There are so many factors that can be involved. Noting your current Ca and Alk is one thing, but SPS really crave stability, so how that numbers changes on a day to day basis is actually more important. Heavy parameters swings IMO generally cause more of a sudden tissue recession, so I would lean more towards trying to change the flow its receiving and go from there.

ya i moved him, and for my dkh its still at 9 i read the test wrong

I think people have correctly identified the issue youre having. Mag of 1000 is way too low. You can safely raise your mag 100pts perday (from my reading). Try adding some liquid mag and make sure you test regularly so you dont over dose. The mag should be 1300-1400. If you BN has lower flow that is prolly an issue too. They dont like direct strong flow but a moderate indirect flow would be adviseable. Usually this is a problem when they grow out and the orginal flow cant penetrate the branches to the base and it starts to receed and brown out from the lack of flow. Lighting is important, try to not shade it.

sps water quality require parameter stability with low nutrients.

Seachem measures ALK in Meq/L

 

[pimp2daizzo]

can high cal cause this?

and i add mag im going to test it later tonight when i get home, but i tested my dkh again and it read 11 dkh but my other test is still testing 8.

i moved him down to the floor where there is the most flow in the tank but he didn't look much better today, so don't rly know what to think.
