Euphyllia melting

ekandler · Aug 2, 2022

Some of my euphyllia has started to melt. Even ones which have healthy tissue are receding back into the head and melting with about 3 days notice. Some are fine… others are not, but given how quick it’s happening I want to try and stop it to save the rest. Any thoughts on what would cause this?

it’s an established reef (3+ years), SPS/softies are unaffected by whatever is happening.

are you running a UV Sterilizer

How's your parameters? Any recent changes in any of them? In the past, I noticed that if my params changed, even somewhat minimally, euphyllia feel it and react by killing off heads. For me it was lowering my nitrates via carbon dosing. It happened gradually, but I still lost several heads on various euphys. Luckily with branched euphys all is not lost and what survived has recovered and done well.

No UV sterilizer. I’ve run one in the past but not for 6 months or something like that.

My main 3 are pretty stable, I use a Trident with a DOS for alk/calc. My nutrients are as stable as I can get them ha I run a filter roller, fuge and skimmer but sometimes stuff is just wonky. I’ve never understood it, don’t change my feeding schedule or nutrient export methods but nutrients goes insane.

Yes, looks pretty good except for your PO4. Seems that's bounced around from lows of 0 to highs of 2+. Not saying that's the definite cause but as I said I did see sim behavior when I was CO2 dosing. No3 came down but so did my PO4. Had to wind up dosing PO4. If not this then possibly some contaminant in the water. Again, euphys being overly sensitive compared other SPS/softies.

I’ve heard keeping magnesium 1500+ benefits euphyllia. Where do you keep
Your mag? And Have you seen even evidence of that working?

Right around 1500. Can’t say if it is helping or not though. My euphys have generally been pretty good. As I said only issue I had with them was when I lowered my no3 and po4.
