SPS issues?..
 

Hey all

So I have noticed a few issues with some of my SPS corals. They are losing color on some spots and turning white.. but it does not look like a bleaching white.. kinda off color, if that makes sense. I noticed it on one of the corals.. it looks to be moving slow so I didnt think it was white death or anything. I dont know if its RTN though..(does not seem to be melting off or anything..)

EDIT: I am pretty sure it is not RTN. This is slow and more like off blotches
EDIT 2: I have started to dose a new bottle of "Kent Mg"
New ATI lights, couple months old
Cal 400,ALK 6-7,SALT G 1.24 and mag is around 1250.


Not sure what I should do.. Watch if it gets worse and frag? Any ideas? I could try and get pictures but they are bad angles and not sure if you would see much.. Kinda lost here..

Snap a picture for me.

Maybe acropora eating flat worms? they can produce this type of mess in patches and they can be hard to see.

I also heard spring is the worst time of the year for SPS. Something about them being allergic to pollen. Hope you find out whats wrong.

I will try and get a picture and also try and if I can see any bugs. I dip all my corals before they are added to the tank. Just in case.

Do you have any tank mates that would nip the sps?

I don't think so.. On one of my SPS it looks like a little strip but I did my best and couldn't see anything on it.. So I don't think it would be nipping.. I might need to take it out and do a fresh water bath or something

acropora eatin flatworms can be very hard to see because they are sort of transparent. Make sure you check with a magnifying glass.

I will d that today for sure :) Just need to find the mag glass :)

Thanks!
