acan corals and scoly dying off

[cpayne015]

I have about 275 total gallon in my system and am using kessil 360w now across the board. I transfered both my tanks over about 2 months ago and since all my acans have started dying off and just put a scoly in about 2 weeks ago and its got holes not looking good

parameters

ammonia 0
nitrites 0
nitrates 0
calcium 490
alkalinity 12.5
phosphates bounces between 0 and .25

all frogspawn is doing great growing extra heads, gsp is growing everywhere, all anemones are doing great, hammer is doing fine, goniopora is doing great and mushrooms are doing fine...

have dipped them in rxcoral to see if that helped and it diddnt....

trying to understand exactly what is going on so any help would be great

your alk seems a bit high

 

[J Rog]

Ya, alk seems super high..

 

[3Twinklets]

Agreed

 

[cpayne015]

yeh but why would everything else be thriving...i know they are a little too high

 

[Eternal]

high alk can burn lps especially if carbon dosing or low nutrient system

What's sad is I don't dose either as water changes is only thing I do lately to try n bring it dowm...any other ideas?

Alk agreed. Your darn close to double NSW for what reason? And perhaps lighting too intense for these. I notice my acans take a lot of time to acclimate to my LED's and your kessil are probably a fair bit brighter than my set up. Blastos area also among the led sensitive if you have issues with those too...

lighting i started off at 40 percent intensity and went up to 45 percent so far where it starts out at 15 percent. these acans looked great for around 10 days until now
