weird SPS issue

[Nwest]

So recently I have had a couple sps not looking so good. it seems that from the tips are brownish colored stuff that looks like algae almost. Now my pink birdnest that was doing amazing as all of a sudden turn to nothing....Here is a pic of it. here are my numbers that i have tested so far. I did recently start running bio pellets but started with 1/4 of the recommended dose. Its weird some coral has just stn'ed while others a doing amazing! please help figure this out...

Ph-7.9-8.1
Alk-3.35 meq
cal-430
nitrate-4.0
phos-.09

What's your mag, phos and nitrates are a little high (but i'm guessing that's why you are running biopellets).

I recently expereinced the same thing with some Birdsnests, I had high Phosphates and recently started using a Reactor with GFO, I think it took out Phosphates too quickly and some corals react negatively to that sudden drop in phosphates, I could be totally wrong, I would also watch your ALK and monitor it closely...Any drastic changes to the system I have noticed is a bad thing, Even if your Nitrates and Phosphates are high, reducing them slowly is better than quickly I think...and my guess is your experiencing the same thing I did, reduced phosphates to quickly via the Biopellets.

I would be double checking my ALK, Reducing the amount of Biopellets (never used them so not sure how that would work) or running it every other day or ever few days, like few days on, few days off, so that it slowly reduces Phosphates/Nitrates rather than a big reduction...and Do a partial water change to make sure your parameters are in check...thats what I am going to do...

If there is any living tissue on your birdsnest, frag it and see if you can save it, thats what I did...

Bummer though, sorry we had to learn the hard way...that sucks

yea. Also a few other corals I am having slow tissue narcosis on. never had it before. so I am going to stop running the biopellets..

Ditch the pellets. I ran them and a few acroporas and birdsnest died shortly thereafter. They started receding tissue and were covered with a brown slime, starting at the tips. I also had a cyano outbreak which is rare in a very very established tank. As soon as I pulled the pellets all colonies that hadn't bit the dust fully recovered after cutting off the brown slimy tips! The pellets simply don't work positively for everyone.

i would agree to this and i went off to Zeovit and never regretted on that

same here. Was trying BP and get exactly the same "effects" - dead/half dead corals and cyano outbreak. I think BP might work only for systems heavily overloaded with nutrients.
