Browned out acros overnight

[GHOSTLY]

Yesterday I had an incident where my anemone got shredded into the tank. I was forced to do a water change and change things around drastically but looking today many of my acros seem darker and browner. Is there any way to bypass this or do I have to deal with the corals being browned out and coming back again? Maintaining everything steady atm but had to do a major correction yesterday. Many of them are holding color but look much less bright than before
Cal 420
Alk 8.3
Nitrate 5 (dropped from 15)
Mg 1400
Much less vivid than before

Water change and run some carbon is the only thing I can think of to do other than waiting.

PS Tank looks nice. I'm surprised you had a nem in there. I won't keep nems with coral any longer.

I am getting burnt tips at my current alk so id be hesitant to do more wc. I did one 2 days ago and 1 yesterday for the anemone. I threw some cuemipure in

Sounds like you already have things covered as best you can.
Not sure how WC raising alk enough to cause burnt tips unless your using a salt much higher than your target for the tank and not adjusting it first. I use a salt that mixes close to my target so I don't have to make adjustments.

Sounds like something isn't right....maybe low nutrients or overfiltration.

Can you post your current water parameters including N&P?

Also, how are you cleaning an filtering the tank (aside from water changes)?

Do you have liquid N&P that you can dose?

Undoubtedly there was an ammonia spike associated with the death – corals use that as food (dissolved nutrient) which can cause a spike in dinoflagellate growth (Symbiodinium, don't panic) and that leads to the "brownish" coloration.

If the tank is stable and this was only a momentary thing (as it appears) they should recover in time.

There was definitely a swing in nutrients. I did a water cuange the day before but because of the anemone incident I was forced to do another. Current nitrate is 5 and phos is around 0.08. The drop was about 12-15 for nitrate. Things have stabilized and are put into my old parameters but Ive had to incorporate purigen and chemipure to clean up impurities

I think it wasnt the salt (same salt) but the rapid drop in nutrients. I also did mix the salt in only 30m so it could be a slight swing from salt still suspended in the water

Well, I'm specifically talking ammonia.....you may or may not have also detected it in testing later as a nitrate spike. Either way at least some of that ammonia spike would have been absorbed by your corals, leading to the browning.

IMO don't over-react by over cleaning the tank or making any other drastic change trying to force some kind of correction. Just try to get the tank back to the stability it had before...mostly by doing what you were doing before. I would discontinue the extra filtration as soon as you think it's possible.

If you have to do another water change, I would consider dosing the new water with nitrate and phosphate to your target levels.....IMO target ≥ 0.10 ppm for PO4 and ≥ 5 ppm NO3.....that way the tank's levels are unaffected (or boosted).

If the water change is just for removing debris/detritus, then siphoning through a filter sock and putting the cleaned water back into the tank afterward is another option that won't negatively impact nutrients.

I don't think you have any "contaminants" to worry about.
