Hi Guys, Can anyone let me know why this Wild Aussie Acro is not colouring up. Its getting browner by the day...is it too much PAR or too little?
My nutrients are Nitrate 5, Phosphate .03 which are slowly coming down as my dosing increases (NP Batch Balance).
I have no idea of the I.D of the coral just was told high light which it is under a PS Hybrid which is cranked up to 70%.
All my other SPS are doing okay now and getting polyp extensions.
Thanks in advance.
Miles

It's dead been taken by algaes? Take a new pic without the blues.

No def not dead...I have two browned out now.
My nutrients are po4 .015 no3 1
Lights cranked up to 75% (hybrid pacific sun 4 no t5/ 2 no 145 watt led)
ICP test results was the phosphate high which is was at 0.13 at the time and slowly lowered to above but still scored 97% on all other.
Only other thing is my trace element may be high or low??
Please help if you can guys? I am feeding the tank heavily but not the corals much?
I dose NP Batco which is 2ml per day on 400litres which is making the nutrients lower but doing things steadily. Have full coral polyp extensions as per pic to follow.

Is it nutrients? Lighting? Trace elements...should add KH is solid at 8.3

Wild colonies sometimes never keep their color. Sometimes they color up a different way. Don't take it personally if this one never does anything. If everything else is colored nicely, then don't worry about it.

One is a wild one the other is not which concerns me. All my other acro are doing very well.just the two white which one has total polyp extensions the other the polyps are not massive...... So when I bought these are they in a stage of fluorescence I.e close to bleaching?

Agree with jda, esp with wild colonies making the jump from the wild to a captive system and artificial lighting. Sometimes just the initial stress from shipping can make an Acropora brown out or fade, sometimes the coloration it had in the wild will never return, sometimes only the new growth will be colorful while the original parts of the colony remain drab, or the whole thing can start to shift entirely. Taking a guess, but I believe what you have there is A. macrostoma. If all others are doing fine, don't frett over it too much, just give it time and love.

Thanks guys was told one was Acropora Paniculata.....these both came from sustainable Reefs in Australia...One is 2nd generation I think and the other more brown is wild.
All my pink Lemonade/ Strawberry shortcake/ Tenius and Stag bought from the same batch are doing really well. Just the whites although as my Po4 (0.015) and NO3 (1) drop I should imagine they may get better.
Just struggle testing my trace elements and getting right.
I dose Tropic Marin Np Batco Balance which is starting to take effect now. As you guys may know it contains some trace elements (Tropic Marin K) so have been dosing the A- at the same dose to provide a balance...problem there is Tropic Marin are vague on quantities in N Batch Balance...I believe it is 1ml in 1ml but I suppose my next ICP will tell me? Cheers Miles

Everybody struggles with testing trace elements. Don't do it. Just change water with a high quality salt in regular intervals and melt natural coral skeletons in a CaRx for the large majority of the elements that are needed. Nothing more than this is needed and it also happens to be the easiest and cheapest way (probably) to achieve it.
