Magnesium and Salinity level for Euphyllia

[Peter Brom]

HI,

I'm running my nano max tank for 7 months now and except for my Euphyllia, all my other corals (like Zoanthus, star polyp, and Clavularia) are doing very well and growing.

But I have a question about the Magnesium and Salinity level for Euphyllia since they aren't doing great. The tentacles are halfway out and they retract back a couple of times a day. So after reading some information is it correct that the Magnesium level should be around 1.500 and the Salinity level 1.025 - 1.026 ?

Placement Euphyllia
Bottom of thank and the tentacles are slowly moving in the current

Water flow (Reefwave 25)
Low and random

Light (Reefled 50)
90% Blue and 10% White on 18k

Water parameters
Salinity: 1.024, MG: 1.300, Nitrate: 5,5 ppm, Nitrite: 0.009 ppm, Phosphate: 0.2, KH: 8.2, Calcium: 466, PH: 8.3, Ammonia: 0.00, Temp: 26.1 Celcius

Thank you for responding.

All your numbers look pretty good. Mag at 1300 is ok for them. Could go a little higher but that isnt causing retraction. I would look for something bothering them. Mine were retracted for a bit and i found vermitid snails on the backside of their stalk they were on. Those webs they put out irritate them big time. Also if you have a beam light like a kessil you dont want them getting the beam straight at them but have them more off to the side even if lower in the tank.

I have a "mixed" reef 3 hammers, 3 torches, 2 duncan, zoas, rfas, photo gorg, blastos, my stuff is doing well since I came back (march) great polyp extension and some growth moderate flow where torches and hammers are. Hammers and torches receive about 6 hrs of 175 par roughly 18k (at least thats what the AI app tells me). I think your nitrate is to low. Any idea of the actual par? My salinity is 1.026 15ppm nitrate, phos .15, mag 1440, calc 450, dont really test ph but last time i did was around 8.2. Weekly 7g water change.
Could be mag and salt.

you can't compare euphyllia to the other corals you mentioned, they are very hardy soft corals that can grow in various conditions, but euphyllia is much more picky, totally different corals.

Its very hard to guess the problem based on the description, I would suggest to take a picture in white lights so we can get an idea.

Thank you, i do have 2 snails. Will take a close look at them it they are bothering the Euphillia.

Not moving snails. Vermitid snails. Look like this.

Love the bottom of euphelia. The tenacles provide coverage i think.

Ah ok. Got it thanks. Indeed there are a couple of those and they are black. Will remove them.

1500 ppm sounds inappropriately high to me for magnesium. No euphyllia in the ocean gets magnesium nearly that high.

That mg is kinda high.
I know alot of pepole say they can be hard to keep.
But my tank has gone through major swings and they are happy as can be in my tank.
I've found they don't really like high nutrients more lower stuff when talking alk,cal and mg.
For the past 5 days my alk has been in the 3- 4.0 range and they haven't retracted or anything.

My opinion I have been keeping my magnesium 1450
Phosphate 0.08 rang
Nitrate 10-15
My torchs being looking happy
You got to see what your tank like every tank it’s different
I find my sweet spot

Hello,
I enjoy reading all your articles and comments, respect for your efforts to help all the fans around the world. I have the same problem with magnesium -- it's at a level that my brand new Salifert test can't read. It seems to show over 1500 and up / I measured it 3 times in a row /. The aquarium is 3 months old / 150 g /, there are 2 clown fish, 3 euphyllias and one zoa, which seem happy at the moment. I haven't added any macro or micro elements so far, just changing the water 10% every week. Am I not doing the test correctly or is the salt I am using inappropriate / AF reef salt /. Is there a way to reduce magnesium in an aquarium or change the salt?

So... the tab on the left is what really should be the topic of the day here. "Morning woo...", assuming the last letter would be a "d", I can't help but to wonder why that is open next to "reef2reef" XD

There is a lot which shouldn't be the case in our aquarium compared to that of the sea water, but from what I have read a lot of people actually have it around 1400-1500 (going up to 1500 range) and their torches seem to be thriving. I don't think the magnesium would do causing the issue here.

I don’t doubt they do well there, what I am doubting that levels that high are needed.
