Green Acropora turning Brown

[daniel_mourra]

Hello! Any advice with this acropora turning brown in the tips and parts of the base?

It was added mid April… strated browning 2-3 weeks ago.

Water Parameters checked with ICP and everythin in the green except iodine a bit low but still within range.

Tank is a 200 Gal Peninsula
Nitrates 7.0
Phosphates 0.07
Ca 450
Mg 1400
Kh 9.0
Salinity 35.0 ppt
Ph 8.1 on average

Lighting: was on a 170 PAR zone and I moved it yesterday to a 210 zone. (XR15 PRO on AB+ Spectrum)

Flow: Was on 2 Jebaos MLW30 at 90% high flow area almost 3200 GPH and now upgraded To 2 MP40s runing at 65-85% power and its still in a “high flow area)

Any advice?

Here are my ICP results from 1 week ago.

Looks to be blue on photo,raising your par lvl like you have will help.don’t think there’s a lot more you can do

If those numbers are all correct, your problem is probably in lighting. That's not much light for an acro trying to re-establish itself.

Full tank picture?

What PAR would you recomend?

How long has the tank been running.
Are these the first SPS coral you've added?

I somehow missed his first post. Thanks.

What PAR would you recomend?

I keep acros at 250 and up. Some can be kept in lower lighting. Move it up slowly and keep a sharp eye on it.

Full tank picture? What are your nitrates? Alk?

Nitrates are 7.5 and dKh is 9.1

Its not the first Sps… tank has been runing for 1.5 years…. All other corals are perfect.

Got it… how slow is slow? I am new

I cook my acro w xr15 g5 pro’s X 2 ab+ 100% schedule intensity for 10 hours Red Sea xl300 and they could take more PAR. I like the colors and growth. Don’t want things too much in a hurry.

Where was the acro sourced. Ask them about their lighting.

 

[Bob Weigant]

Acros can be tricky but from what I saw you need more light. I tried running an XR 30 on my 120 and it wasnt enough

Great idea

If i add rocks and raise it higher to a higher PAR would it be the same as adding mire light fixtures?

bump the par up. I’m running 275 par on my bottom glass (but I do run wall to wall sps). Did you see the mother colony? Is it suppose to be green? Some corals turn green under stress and then after acclimating or getting better return to their original colors. Also don’t raise it to higher par too fast- too much light can brown just like too low light.

It can but How many lights do you have and what are your dimensions
