could be due to many reasons. maybe background info of your tank could help. for example. how long has it been set up, whats the nitrates, nitrites and ammonia readings.

Could be due to pests do you see any small insect like creatures crawling? best is take a torch light and check at night.

[Daniel Poh Yang Zheng]

Ammonia is 0, No2 is 0.3, No3 tbc.. KH is 7.6

whats ur specific gravity. Seems like ur parameters should not be the issue.

How long have u gotten this zoa?

[Daniel Poh Yang Zheng]

Water is Abt 1.021... Does PO4 and No3 affects? I am having a green algae and brown algae out break nw... I got it Abt 2 to 3 days

Den could be pests. Try looking at it at night

[Daniel Poh Yang Zheng]

Even the gsp does nt open... So it can't be just pest...

Could be something in ur water. maybe some chemicals. u could run carbon for a few days and do water changes

Bro, if you have NO2, that means your tank has not finished cycling yet... just hang on and wait till it becomes zero, then measure your NO3 and PO4... the more coral you add in now, the more dying coral you will have and the longer your tank will take to be ready...

[Daniel Poh Yang Zheng]

So are the coral dying or it is not the ideal situation for them to open up?

I am already running some carbon in my IOS area..

if they dont open up long enough they will die... the question here is how long is long... i.e. will your water improve faster than the rate it die so that it can recover...

[Daniel Poh Yang Zheng]

Okie..guess I need to have my water change and water check...

bro, after water, next thing is light and flow to pay attention to...

[Daniel Poh Yang Zheng]

T5 nt enough? Flow is average didn't point my wavemaker directly at the gsp or zoas

[Clement Chen]

T5 should be fine. If not enough light u will see the zoas stretching out towards the light

Bro, ur sg (1.025) sounds okay to me

mine open up very nicely when sg is 1.025

Hope u have solved ur problem though

[Daniel Poh Yang Zheng]

My no3 is Abit high that is why it didn't open up

From your post, N03 is 50ppm. Phosphate is 0ppm. This unbalance is an issue & may be the reason why your N03 remains high. This could be related to a phosphate binder added?

In my case, my GSP don't open when nitrate starts to creep past 30ppm.

From my understanding, there needs to be a 16:1 (Nitrate : Phosphate) relationship for the bacteria to process the waste nutrients effectively.

At such nitrate levels, at minimum, the phosphate needs to be detectable (not entirely 0). Do double check, else allow the phosphate to increase temporarily..

I only have activated carbon...
