Help! Acans dying and euphyllia upset

[Noahdoe]

Hello recently (the past two weeks) I’ve noticed my acans receding and losing heads from the outside, however remain quite happy looking. This has gotten worse the past week and I’ve lost two colonies and now my euphyllia looks bad. No swings in parameters so I’m unsure what is going on - hoping someone has also experienced this?

How's your flow and lighting? I'd be curious how your pH is doing as well. You could bump the magnesium up by about 50ppm too.

This is my hydra schedule it’s sitting a good foot or so above the tank and the acans are at the bottom of the tank. They’re not in high flow areas and if they were upset about these two things I would’ve thought they would be retracted and not losing heads from the outside? I’ll test ph now

PH ~ 8

What I would try in this situation: run fresh carbon, a little shade, make sure that flow is not too high and that torch doesn't reach them at night. Feed them.

Check salinity meter calibration, but they are tolerant is SG is within 1.023-0.030.

They can take higher phosphates and nitrates, if they do not get a lot of feeding.

Check if there is some ammonia, just in case, corals are not expanded. Check stray voltage in the water, but this is unlikely.

From the state of the rocks, maybe run some sludge remover, bacterial supplement to unclog pores. Dr. Tim's ReFresh and WasteAway worked well for me.

Unlikely, but maybe bacterial infection. If acan is removable, some coral dip for this.

Are those David Saxby settings? They are often super low light, while LPS don't need too much light, I would take some par readings.
Saxby runs 94 AI pucks over his tank, that is why his settings are so low.

How quickly did you drop nitrate from 20, and what method did you use?

What is that graph from? Reefbot? Mastertronic? Ion Director? Want to know because I'd like to purchase one. Sorry, I've got nothing to say about the corals that hasn't already been said. I'm a coral noob and came to learn.

Thankyou for your reply, I’ve been feeding them since they’ve been looking bad. Previously I was only feeding the coral once a month because I thought it wasn’t necessary. Will any coral dip stop the bacterial infection? I will check ammonia although I only have an API test kit for this.

thanks !!

Yes they are his settings, I set it up 2 years ago when I got the tank and I didn’t really know what I was doing. I’ve seen decent growth from my monti, and haven’t lost colour. I’ll attach a pic of the tank before everything started to look bad. My light is a hydra 52.

I have been struggling with GHA since the tank has been set up so like 4 months ago I started dosing vibrant. I didn’t see any negative effects with coral so I don’t think it’s causing this issue. But when the vibrant killed the gha on my rocks it caused the nitrate peak. To reduce this I dosed a little nopox (half the recommended on the bottle) and it dropped. This was about 2 months ago.

thanks!

This is from an app called AquaticLog. It’s alright… I started using it just for its automatic graphs
