Losing torch corals

[kingyjk]

Hi, wondering if someone can help me diagnose my issue. I've lost 3 torch corals over the last few weeks, my tank is approx 2 year old and before 2 weeks ago everything has been fine. All my other corals seem fine and happy (only seems to be my euphyllia)

My parameters:

Calcium 450
Phosphorus 0.03
Magnesium 1400
Alkalinity 8
Salinity 1.0025

Tank size 90litres

I been running a 20% water change weekly for 2 years and test weekly with salifert and hanna test kits.

Light is redsea led 50 running mix of 70% blue and 70% white

I've just dipped one of my last torch corals which seems to be slowly dieing. I've noticed brown buts on the end of the tentacles which didn't come off when I dipped, I'm not sure what that is. Anyone have any ideas?

Hard to tell from the picture. If the brown stuff is a bit slimy, it is a disease, although the name escapes me. Are they getting fed?

Here is another picture I took of a coral I lost a few weeks ago

I used to dose ab plus and I tried reef roids for a while but my nitrates and phosphates really went up and my local reef shop told.me my corals don't need food, only correct parameters light and flow so I stopped feeding

Well they are wrong about corals not needing food imo.
Phosphorus or phosphate .03 units??
How about nitrates? Last photo looks like some bjd. But probably the coral was stressed and losing tissue from insufficient nutrients over time and then succumbed to disease.

Is salinity at 1.0025 a typo? Get your phosphate to .05-.1 and nitrates to10-15 ( I didn’t see it listed). Torches need moderate random flow and moderate par.

Thank you for the advise, I will raise my Phosphate and start feeding again. Yes Salinity was a typo and my nitrates from what I can tell from the slifert test kit is 0 so ill try get that up but I find it hard to tell the reading with the colour chart.

Yes, practically no nutrients is the major problem here, get those up and you’ll see some happy corals. Good luck.

Brown jelly disease, cipro or kfc dip can help
