Pink goniopora issues

[Craigdillman]

I remember you saying your temp spiked up to 85 or something has that got all fixed cause if your temp is outa wack or swinging that can cause all these issues

While I am in agreement there may be a water issue, I would also recommend moving the piece to another location to see if it makes a difference. Mine (same colour) has always opened up in every location, however it opened up more in some spots than others.

My vote is high phosphates do you have a accurate test kit Jason?

[jason604]

No I do not have a phosphate kit. I do believe I have high phosphate because I have green hair algae everywhere. I have the API phosphate remover bag running passive on my sump with a carbon bag. I guess I should go buy a salifert phosphate tester. My params r alk 7, cal 310, mag 1100 ish. I'm using salifert mag but I can't seem to get cal n mag up to a proper level. My big sps colony got messed up cuz my doser died but after I chopped it up and fixed doser there hasn't been anymore RTN. Water temp is now a stable 79. I tossed the starfish out because a hammer n a frogspawn just closed up. I will do a water change soon. But I can't explain my goniopora closing... Been closed for 1-2 months and my tank was thriving then. I do feed my tank reefroids mixed with phyto 2x a week.

Sounds like you just explained it. Calcium is quite low, mag is low, and high phosphates. All of that combined is sure to do a number on your tank. Id do a big water change asap

That and the fact you had a doser and everything was probably pretty stable and now it's probably all outa wack

What do u guys do to lower phosphate I u don't wanna run a reactor? Is me running the phosphate remover bag passive in sump good enough? I'm trying to remove as much green hair by manually pulling it out on each water change as much as possible. I put 4 teaspoon of seachem magnesium mix with ro 2x a week manually in my 75g but that doesn't seem to be able to get it to 1400 lvl. I'm scared of putting too much too fast n shocking my system. Did it set it up to my doser yet because it's not at the lvl I want it to be.
