[nick96ss]

i noticed yesterday that part of my green pocilipora is dying off. checked my parm tonight and here goes
ph.....8.2
nitrite ...0
nitrate.....0
ammonia....0
calcium ....450
kh....8
alk ....2.8
usual temp is always 79 today it was 81
don't have a phos test kit
any clue ? could it be the temp change ?

how is your flow? any pics?

 

[SI REEF]

Get the phosphate kit. Could anything be stinging it?

 

[nick96ss]

it has been in the there for a good 6 months never had a problem with flow
as far as stinging i don't know
i broke off the piece that was dying i'll keep an eye on the rest of it
try to get pics

whats the measuring scale for the alk? seems possibly low.

 

[Aqua Pro Builder]

stray current?

 

[nick96ss]

i moved it to another spot with more flow
it seems to be ok i'll check again tonight when lights are on

 

[Wes]

poci's grow branches very close together, as they grow they require more and more flow. IME, If flow is lacking, they can grow to a point where the branches in the middle are not getting enough flow and start dying off.

 

[nick96ss]

i didn't move it up or down in the tank just to a better flowing spot
want to see how it works out there
wes i see what your saying, the spot that was dying off ,seemed it did lack flow
the other side of it is healthy
i really hate to lose it. it's a real nice piece

If your alk is 2.8 is way to low I had the same problem with my corals and Alex from AE told me that it could be the alk.He did a watter test and he was right alk was 3.8,I bought the buffer kit from him and bualaaa my corals stared to come back to life well those that were not completely death so if I was you I will deal with the alk.I am not an expert I am a newbee but I had the same problem.

his kH is 8 which is fine.

the 2.8 sounds like a mg/L measurement

 

[nick96ss]

yes wes your right on the measurement
this is what i came up with on the salifert test kit chart
kh 8 and 2.8 on the alk
now i'm confused is it low
the chart numbers stated i was in around where i needed to be

Are any other SPS dying? Is it just the one coral?

It's not temperature since that small difference wouldn't affect SPS. Above 85 degrees is the danger/dying zone.

If it is just the one coral, then like Wes said it probably is flow.

 

[nick96ss]

i'm sorry it is only 1 sps the others are fine
i'm sure wes is on the money
