Little white spots on Sunny D colony ID required [emoji106]

[Jd250]

I've had a Sunny D colony now for 12 months all started with 2 heads now I have around 200 , I've noticed small white spots on the shafts of the zoa , they have remained closed for around 4 days , my tank is 90% SPS and doing amazing apart from the sunny Ds any help would be great [emoji106] cheers fellow reef junkies .

Not to keen on coral diseases but appears to be zoa pox. Hopefully someone with more experience will chime in. But that’s what it appears to be to me.

When we had sunny d's the under side had speckling like that but it was the polyps pattern underneath. I'd be looking at chemistry swings, our sunny d's were more sensitive then our other polyps with swings in alk, etc. I don't see speckling on the closed orange zoas next to the sunny d's.

Hi thanks for the reply yeah I did have a spike in alk from 11 to 14 everything else is perfect I have quite a few different zoas and they are not affected . Do u know if it can spread to SPS as 90% of my tank is SPS ?

Thinking about it u could be right as I have to colonies of Sunny D both opposite ends of the tank and both closed up yet all other zoas and SPS are perfect so u could be spot on ....

I'm thinking chemistry is the problem. Let the alk come down slowly. I don't believe it's a pest or a disease given the pics and information provided. Give it time and hopefully they recover for you.

Yeah I agree cheers bud you know how it is years and hours of time you freak at the smallest thing

Nice !!!! U run on no substrate ? And is that a monti on the base ?

 

[DSC reef]

Bare bottom with montis, chalice and zoas as substrate. Lol. Thank you for the compliment.

Hey buddy u was spot on I've lowered my KH to 9dkh and they are looking great [emoji106]

 

[Jd250]

I was focused on a high KH for my SPS excelerated growth but obviously my sunny Ds did not appreciate

Glad there looking good!
