Hammer coral closing/shrinking(?)

[Uzair Aiman]

Hi. First thing I have to say is I made a mistake (I guess), by feeding my clownfish some pellets soaked with mashed garlic. My clownfish had white strings from it and I suspected internal parasites. It came to me after asking in R2R that feeding garlic was a no-no since it only just entices eating for the fish.

Now to my problem. I mightve overdosed the tank with garlic water or some sort. And that was when my Hammer coral started to close/shrink. I suspect the garlic is the cause of this.
I fed my fishes garlic the last 2 days and yesterday. I stopped yesterday after seeing it affecting my hammer. I did a 20% water change ( I have a 20gallon AIO tank) and waited the night. It seemed to be still unhappy. What can I do to help this fella out? Im scared Im losing him as he is my first LPS coral. My GSP seem to be fine right now.

Also,my tank is undergoing a Diatom bloom. Idk if this affects it but I dont think so.

Should I do more water changes? Should I leave it be? ( I added some activated carbon to my filter). or what else should I do?

Picture below shows how it looked when it was opened up (for comparison)

Liquid garlic by seachem or brightwell
Assure the following are not elevated:
Water flow
Light
Salinity
Alk
Calcium
Ph
Nitrates

I found mine needed to be spot fead to be healthy.

I just mashed some home garlic and soaked my pellets in it :').
To be honest, I only have 2 testers right now which are ammonia and nitrite. I use the Salifert ones.

I havent changed anything regarding their flow or light cause I didnt move them or any powerheads.
I maintain my salinity at 1.023 - 1.024.
I guess my Nitrates are low cause I did a water change.
Ammonia suddenly read <0.15ppm but Im not sure if its an error or something.
Nitrite 0.
My alk tester is on the way, what numbers should I expect?

should I do another 10% water change?

I see. How often and what do you feed it? Ive mysis shrimp on the way. Right now I only have fish pellets and Brightwell s Zooplanktos-s.
How long did it take for it to be healthy again?

Salinity- 1.025 and if on bottom, get it away from sand which will irritate it

Okay, Ill increase the salinity on the next waterchange (this weekend) to 1.025. Its not on the substrate its on the rock but near the substrate
