Acan help

The angelfish could very possibly be nipping them. Maybe you could try putting him in a time-out (in a sump or acclimation box) and see if the acans start to bounce back?

But, I do agree you should have SOME nitrate. Not high, but detectable. It's a tight rope, for sure.

Edit. Ah, did the nitrates drop that much while the acans were in the tank? What other corals do you have, anything else react after you brought them down?
Yes they were in the tank while it dropped and i believe the nitrates were killing the acans as they were losing color and receding and i do have neon polyps greenstar polyps and zoas and those are closed too

Except the neon polyps those looks healthy
 
Ive been wanting to sell him or get him out kf the tank but im not sure how to catch him

Well, I'm not completely convinced he's the culprit yet. Coral beauty are usually one of the "better behaved" dwarf angels...though the risk is always there.

I also doubt the light is too strong.

I'm thinking it might be more likely the nitrate issues.
 
Nitrate reducing pad my bad and yes
Can you send a link to those pads? I would double check the nitrates. Zoas like dirtier water. Corals do need nitrate and phosphate in order to survive unless you are dosing amino acids. That is a HUGE strip of nitrates in a very little time. The initial swing of nitrates probably really aggravated them and stressed a lot. And then the non existent nitrates are starving the acans and corals. I would suggest you cut in half of what your doing for nitrate removal, maybe add nitrate to the system and try to keep them steady around 2 -5.

Yeah i havnt seen him peck at anything but the algae on the glass but ill make sure to remove some of the pads and media

Ill double check on the nitrates and yeah i do feel like ive kept my water too clean and how can i add nitrates? Im not being sarcastic or anything so like leave more uneaten food?

Food adds phosphates, nitrates come from fish poop. So you just need to cut back on what you are pulling out with the nitrate sponge. You can add nitrates by dosing, but that's a slippery slope of number chasing if you are actively adding and removing them at the same time [emoji15]

I cant find them but i believe they were imagitarium nitrate reducing pads

You can feed more to help or you can get products to dose nitrate itself...Brightwell Aquatics NeoNitro Nitrogen Supplement for Ultra-Low Nutrient Reef Aquarium Systems, 500 mL https://www.amazon.com/dp/B00Y01KXWU/ref=cm_sw_r_cp_apa_UwokzbHFENRSX
This is an example. You could dose amino acids as well.

There's no way you went from 160 ppm to 0 ppm nitrates in 4 days. That would be almost impossible to accomplish. What test kit are you using? Now you feel like you've kept your tank too clean, yet you say you had 160ppm nitrates? Is this post for real? If it is, I would suggest getting some good test kits, or taking your water to a local fish store to be tested and start there. The acans could be doing poorly from any number of things, including but not limited to, bad water conditions, light, flow, acclimation, etc... What other corals do you have and are they doing well? Start with getting some dependable test numbers and go from there! Hope you get it sorted out.

I agree to this. I still recommend checking nitrates again. Different test kit? Lfs?
 
Agree nitrate issue. Stressed them enough for them to receed. Hate to say it but your on the edge of losing this coral,

Its a 20g im dealing with and using an api marine test kit i loaded it with the pads and media and also did the water change but i also do think i did the test wrong
 
Why don't you test nitrate again and let us know what it is. [emoji4]
