Hi, recently corals in one corner of my tank have been dying and I need to know why. Mostly euphillya but also a montipora digitata.
I noticed my hammer corals weren't doing great, they were less extended by the day and the skeleton started to show at the base. Now my frogspawn is doing the same thing and my digi is bleaching out.
I had a BTA in that area that hasn't been doing good lately, also shrinking and I decided to remove it today before it died and poisoned everything.
My parameters are stable: 8.7 dkh alk, 400 ppm calc, 1350 ppm mag, 1.026 salinity, 10ppm nitrate and 0.1 ppm phosphate, pH is around 8.15 when I test around 4pm.
Now I have some hypothesis:
- I have a Prorocentrym dino outbreak, I know they are poisonous and run carbon to counter this. Problem is, my other corals are fine, including a torch coral so I have doubts about this causing the problem. I am in the process of treating the dinos by raising nutrients, ordered waterglass to cause a diatom bloom, 5 micron filter socks to siphon some of the dinos and recycle water, going to dose pods, phyto and bacteria.
- I have not been doing water changes because of the dinos, I dose kalkwasser, magnesium and nutrients to keep my levels stable each day. Again, other corals don't seem bothered so I don't think this is the issue.
- My bta was releasing toxins because it was dying near those corals, affecting them more and such killing them. I'm not sure this is possible but something I thought of.
- Disease of some sort, although these corals have been in my tank for a long time and have been doing good, I did notice my digitata getting a white spot that grew a bit every week on its underside. I looked for some nudis at night but didn't see anything. Again, I am no expert and am not sure if a disease could affect both Euphyllia and SPS.
I would love to get some input on other reefers and their experience, I don't think this is a coincidence and would like to take action before all my other corals die.
