Chalice RTN?

[studentdriver]

I have about 12 around 1" Chalices on the sand bed. The "Pink *******" just RTN'ed out of nowhere. It just started to flake off, within 2 days there's nothing left but pure white skeleton.

Parameters

Temp 76-78
pH 8.0-8.2
ALK 8.5
Calcium 480

Have anything like this happen to anyone's Chalice?

What are the magnesium and salinity levels?

 

[stedfast82]

well if there is any flesh left put it in low flow and low light ive seen chalice come back from the dead check your mag 1500 is cool.

 

[studentdriver]

mag is at around 1300-1350
Salinity 1.026

I did put it in a low light and low flow area after it RTN, but it continued.

 

[Reef UP]

I've found my chalices to be happiest in the 1550-1600 range and my calcium is 500 alk 8.5 salinity 1.027-.028

Do a google for interceptor and chalice. I had chalice recession, though slower that you noted, bubblegum was first to get hit, Cyphastrea followed and then the masses. Suspected villain is an invisible bug that interceptor treats.

Is the interceptor used for Red Bugs? I have a bunch of SPS, I though red bugs will affect the SPS more.

It doesn't have to be red bugs that are bothering your chalices. Sometimes it is amphipods or some other type of pest. Interceptor will take care of most "bugs" in the reef. On another note, I keep my Mg levels pretty high and my chalices seem to love it. 1500 seems to be the best for me.

Watch your PO4 also.

Maybe it's neighbor stung it.

i had that also. it doesnt sound like what happened to the pink *******.
i would say its mag/ alk related.

I had the same issue, couldn't figure it out until I noticed my Blenny munching on my chalice.

You have a good point, the rapid deterioration described is not what happened to me. Alk swing could cause that...

i had a chalice completely receded over night to find that a snail took a nap on it.

 

[studentdriver]

Wouldn't ALK swing affect the more sensitive SPS in the tank first? I'm using a Bubble Magnus dosing ALK/CAL/MAG, I would like to believe it's pretty stable.

it's worth checking you KH. I love my BM doser - you do need to replace the heads depending on use. Do a controlled test of say 30 ml into a vial to make sure you are dosing what you expect.

The other side is that dosing requirements can change over time. my phosphate has crept up and growth slowed reducing my requirements. Caused a slight increase in KH before I caught it.

ive had alk swings that wiped out my lps yet ive still got the sps in that tank.
low magnesium will make the flesh just pull off and float away.
those evil pods/bugs whatever eat from the outside in and it happens only at night.

 

[studentdriver]

I tested the ALK again today and it's at 8.5 exactly where it was last month. I do see bugs/pods around the chalice at night. Anything you can do about that.
