the blue tips are turning brown...

[niquetour]

I bring this about 13 days ago.
My tank is about 1.5 months, with the following figs:
no3 - 0
no2 - 0
kh - 7 - 9 within this range in a week
po4 - starting from 0.2 2 weeks ago to now 0.11
MAg: 1380
Cal: 430

i use bio pellet with phosbans

What is the name of this sps? This one is come from Australia.
The blue tips are turning to light brown which is the same as the body. The light is not enough? I put it in the middle of the tank with quite high flow. Or it is the matter of not stable water? Or high PO4? :fun5:

The first pic is taken today and the sec pic is taken the first day i get it.
The polyps seems extent longer....

You're trying to keep a delicate acro in a tank that's barely cycled. At 3 or 4 months it would be possible with enough light, high flow and much more stable alkalinity.

I see hair algae next to the coral. That's a clear sign your tank is way too young for this coral.

Other than your tank being young, your po4 is high enough to brown out a coral. Aim for .04 to .08 is where I find that I get my best color. With a tank that young you need to let it completely go through its Cycles before using carbon in any form. Especially bio pellets. Brown corals are not bad. Just bad to look at. That coral may always be brown in your tank. Especially if it's a maricultured piece. It's a toss up what they are going to do in our tanks.

Thank you for the advice..
I hope it will getting better after a few months when my tank is matured..
N strive my best to keep the po4 as between 0.08 - 0.04 as possible and keep the alkalinity stable..
