Bleaching?

What yall think.

OK so I'm not sure of the water Para.
As I'm a truck driver but here are some pics.
Wanna know if anyone has any thoughts thanks.

Has one sb reef led. Intensity haven't been up to high I don't think

How close are the corals to the light?

Freakyyfort · Jul 17, 2016

Stag i think is about 4 inches
The horn and thing behind it are at the bottom. And the plating orange one is about 6 or so inches down. All been in there for a month or longer. Haven't had any issues. The stag has actually grown a base.

They are in a 20 gallon long.
They have all been doing great up til 2 nights ago. And last night.. now overnight they are bleaching out..

There are multiple corals in there but only the 4 are bleaching.

Kh is 7 and 5 gallon water change. Done tonight

cdare99 · Jul 17, 2016

I'm no coral expert only have a couple but kh should be closer to 9/10, and also check ph. Kent ph buffer works pretty good for both.

I guess more than that. I was only guessing. They are further down in the tank vs top of light

Freakyyfort · Jul 18, 2016

Kh I've always kept mine at 8 - 9 highest. Ph.. I'm not a coral expert either but ph is more for fish isn't it? And all it is is water movement. I was told to never worry about ph. As long as the waters moving. Ph fluctuates so much through the day and night.

This website explains it pretty good, also check calcium. I don't think it is to low of light but have you tried moving them up higher.

Thanks for the link. Will start looking into it more. Thanks again.

Natural seawater is about 7dKH. I run my sps dominated tank around 7.5-7.8 dKH, but I am also doing a ULNS. PH should be anywhere from 7.8 - 8.4, I keep mine between 8.1-8.3. I am no expert, but have learned a lot for the people on here. What is your levels for Phosphates, nitrates. It could also be RTN or STN.

Listen to this post ♤

Once I get home I'll do some testing and get things back on track

Freakyyfort · Jul 18, 2016

Ph is 8.2

DSPENCE · Jul 18, 2016

I agree with the comment suggesting RTN.....they aren't bleaching, they're losing tissue. Has the temp been holding steady?
I'd try doing a 4 gallon water change each day for the next several days. you can also try a dip in Lugols solution ( iodine dip) to try to stop the bacteria that typically causes tissue necrosis. You may also try putting them in an area that has a bit more flow to keep them clean until they can heal. They look otherwise healthy and you're getting on top of it fast so hopefully they'll pull out of it.

Freakyyfort · Jul 19, 2016

Thanks. I will try. Being I am home now I will start the testing and move them or the power heads in thier direction for more flow. I don't have any dips. Temp swings from 80 to 79.. I think I've seen 78 once since I've had it up.. since Feb. 2016. But I don't consistently stare at it either... I do wanna save if possible so.. I came here

thanks again everyone and any more input is welcome

Try coral Rx or something like that there could be a parasites like acropora eating flatworms.

Transferring everything to my 75 dt. The 20 was a startup grow out tank. Doing a freshwater dip and inspection on corals as they come out. I know it's not the best but... it's all I got right now. The parameters are
Kh. 7
Nitrate 0
Nitrite 0
Ph 8.0
Calcium 430-440
Ammonia <0.15
Phosphate 0

These have been stable since first water change.. going to do a 10 gallon water change today as well.

Hoping they pull through coming over to this tank.
