Needing help

[austen]

Hi everyone, I’ve been battling with my tank over the past few months ( I had been neglecting it due to life changes) my parameters :
Alk 6.5 (slowly trying to bring up)
Calcium 405
Nitrate 5
Phosphate 0
Ph 8

Along with bubble algae and whatever is on my sand bed I have been starting to lose corals heads of torches most of my zoas and sps I’ve been manually removing bubble algae and dosing vibrant as my fox face purple tang and emerald crabs seem uninterested in eating it (corals started dying before vibrant treatment and turned to it as a last resort) I’ve also done a chemi clean treatment if anyone can help ID what is on my sand bed and has any tips or info on how to help save my tank I’m open to anything thank you.

Looks like possibly Dinoflagellates on the sand bed. Does it have air bubbles in it? Best way to tell what it is exactly is under a microscope. There are a bunch of threads on here with how to get rid of them. They can be toxic in the water column and running carbon will help your corals.

You’ll need to bring phosphates up from 0 to at least .1 to help combat them.

Syphon out as much as you can from the sand.

For the bubble algae. I bet the emerald crab is picking at them but there’s a lot in the pictures so his work may not be as noticeable. You can manually remove them however do not pop them. That will only create more.

Keep up on the husbandry, remember it will turn around if you invest that time into it again.

In my experiance with torches, it is more then liking the low alkalinity that effecting them and causing the die off. I have personally experienced a delayed reaction with my torches when a parameter swing happens. Unfortunately sometimes the damage is already done and all we can do is mitigate the fallout. Recommend to get your parameters back up to stable levels safely and hope the remaining heads are resilient enough. What are your magnesium level?

Don’t have a magnesium test kit going to order one and check

Haven’t noticed any air bubbles currently running carbon and a uv sterilizer I’ll check out some of those threads thank you
