I need help!!!

Came home today to my tank looking bad. 60% or more of my sps are Bright WHITE. My toadstool is pulled in along with my clavularia, Duncans, elegance, zoas, and one frogspawn. Xenias aren't pulsing and shriveled, and some zoas are melting away (which they have been, but even more today). Lots of my lps including my open brains, orange torch, scolys, favia, my other purple frogspawn, candy canes, all my acan frags and chalice are doing great and looking fine. Anemone is open and happy, clam is open as well. Mushrooms are good too. Here's some specs. 58g tank with 30g sump. I'm running a DIY led fixture with 56 LEDs on 3 channels running around 75-80% each. Around 55lbs rock, and been running since June. It was a transfer up from a 30g that had been running since Jan 2012. I vodka dose and use prodibio and have been since the 30g. I aim for a ulns and feed heavy. I dose kalk in my ato top off water. I dose zeovit products for the coral and feed the fish usually every day. My phosphates have just recently fallen to 0 on a Hanna checker. They used to run around .03-.06. I have started to run biopellets but have only been running for 4 days. I don't think they could have kicked in in that time as people say they take 4-6 weeks to get going. I did seed them with MB7. I ran a full battery of tests, here's the results:Alk 10.9, salifertCalc 450, salifertMag 1350, salifertPH 8.2 API, 8.1 ApexNitrates 0, salifertPo4 0, Hanna checkerNitrite 0, APIAmmonia 0, APIThis is really bumming me out. I had a nice zoa rock goin with lots of ultra zoas that are just melting. My only theory with what knowledge and little experience I do have is that the water is stripped of nutrients. Also, maybe because of that they have light shock from the water being clearer. I have turned all 3 dimmers down on my lights a little and fed more today. If the theory is they are starving, how can this be? I dose almost everything the zeovit people use and prodibio reef booster, reef roids, dt's phyto for my clam, and on top of that feed the fish. My encrusting montis seem to be impacted the most and they are below mid level and even next to the sand. Here's a pic of the tank before this happened. I'll try to get good pics tomorrow if anyone thinks that will be helpful. Any advice will be greatly appreciated.

 

To me it sounds like alk affects or bleaching. You could try to lower your light levels considering you have LED.

Otherwise im not to sure. A bump to help you out.

 

you are running vodka dose and prodibio as well as Zeovit and Biopellets?

 

I'm running the vodka and prodibio, just started the biopellets to eventually replace those. I'm only using the zeovit products that one uses after achieving ulns. I just chose a different method of obtaining ulns without the zeovit reactor, stones, and bacteria.

 

Maybe you have completely stripped P04 and Nitrates from the water? And this is causing coral distress.

All coral need some trace of these elements. Maybe you have gone a tad to far looking for ulns.

 

With such a sudden change I would consider your ALK level of 10.9. In may be the contributing factor secondary to the carbon dosing, use of zeovite products along with your desire to run an ULNS.

It's a beautiful tank, I sure hope it turns around.

 

I'm 95% certain I know what happened. I use a product by zeovit called zeospur2, it actually manipulates the zoox mainly in sps corals. You can adjust the color of your sps with this product to lighten them up and brighten them. But you have to be careful. I dose 1.5ml every 2 weeks. The bottle sits right next to a bottle that looks the exact same but is called macroelements. You can probably see where I'm goin with this. I dosed 10ml of zeospur2 instead of macroelements. I've seen this before when I first started using the product. At first, you should use half the recommended dose to see how it does in your system. I did the full dose and the same thing happened before as what happened now only this time was much worse. It doesn't so much affect lps or softies or livestock. I did such a high dose that they did get a little mad and some lightened a little. My Duncan's are out again, as well as my frogspawn. My xenias are starting to pulse again and my toadstool is starting to put out some polyps again. It will take a couple of weeks, but the sps should come out of it. They are still putting out normal polyp extension.

 

Glad you found the problem. Agree with Corailline- very beautiful tank.

Personally, I'd strongly consider a water change or two to help reduce the OD.

Either way, good luck!

 

just throwing this out there - with that sudden of a change - did you check your temp?

 

I did do a 15 gallon water change just to be on the safe side, that's always my first line of defense. Temp is good. I checked the chart on my apex and there were no swings of more than .5 degree.
