Please help tank going down SOUTH FAST!

[jason604]

Right after my newly purchased starfish died few days ago my corals wrnt looking so good to BAD. I did a 15% water change the next day but all my LPS were pretty much closed and zoas all closed. 3 days later my sps frags all starting to brown but most of my LPS back to normal kinda. My purple acro started to have base recession this afternoon now only couple hours later the recession seem to have doubled!!! What do I do I don't want everything dying. Here's a pic of how it was not to long ago to afternoon and now.



And here's my hammer that still on trouble.



My water parameter seems to look like its always been just my nitrate are a bit higher than normal due to my skimmer lvl a Lil too low after I removed its foam filter on the water lvl adjuster I think it still breaking in.

Phosphate 0.25. Nitrate 15, KH 7. Salinity 1.025. How can a dying starfish do so much damage. They arnt poisonous right? All effect happen right when it died. I'm planning to do another 15+gallon water change Tmr. My tank is 75g

Please help before its too late!!

frag the sps well above the recession and remount. toss the bottom piece. gives the coral a chance at least.

Yes I have new carbon. How can the purple sps recess so damn fast tho.

It's body is also starting to turn to the color of the recessed part =(. Would dipping it in revive save the base since it just happened in the last few hours?

I would do 80% water change. Then do another one two days after.

Oh damn 80%!!! That's insane! I just fragged off my purple acro now. Scared if I wait till Tmr it will be dead at this rate.=(

Iv been fighting dinos for the last month, and finally got some good advice. So decided to take the advice, and I have done two 80% water changes and one 50% water changes in the last week. As of right now, my tank has never looked better. Corals and fish are happier then they have ever been. And absolutely no sign of any dinos. And if you have had to battle them before you know the **** grows back almost as fast as you can remove it. Just my opinion.

I just noticed recession in a few other acros but they at the body of it near middle of the pieces what do I do? Also what is dinos? Is that another term for recession?
