Flow questions

Ok so I have a 36g bowfront tank, 2inch fine substrate, 30lbs of dry rock, 2 clowns, 1 gamma, 1 melanarous wrasse, 1 flame hawk, and a firefish. About 20 snails tronchs and turbos. I use 2 hob, an ac110 and ac50. Running different media like carbon and chemiblue sponges and biomax. I also have 2 sicce voyager nano stream pumps mounted top left and right facing the lid for some additional surface agitation. My question is, 1 hammer and my dragon soul seem to be closing up. The hammer I can see skeleton on one side if it. The torch doesn't fully extend either anymore. My par for both are like 115 for torch and 80 for the hammer. My other euphilia are doing fine..... so is it possible I have too much flow, the hob filters generate 700 gph turn around , so that's almost 20 times turn around an hour. Should I remove the sicce pumps?
 
It’s not likely too much flow unless they are getting directly blasted.

What are your water parameters (nitrate, phosphate, Alk, calcium, etc)?

There are times when Euphyllia just don’t like something and up and die. Other times, something bothered it and then it’s fine later.

Are any of these coral newer to the tank? If so, do you know if they are aquacultured or wild? Just a thought, if wild corals (and even aquacultured exposed to wild coral) though cant be certain, is maybe Euphyllia flatworms?

Ok so weekly parameters flucates as follows. Cal 430 to 460 , alk 9.3 9.8, mag 1100 to 1300, Sal 1.025 1.026, temp 79 80, ph 7.8, this may be my prob 0 nitrates, phos 0.13, lfs says all aquaculture, and yes all corals have been added within the last month. Current gph is 1760.
 
I would bring the nitrate up a bit and work on lowering the phosphate. What you want is 1-10 nitrate and 0.01-0.03 phosphate.
 
I would try to get your nitrate up. Otherwise most others look good (phosphate a little high but not terrible).

Might just be unhappy corals. Are you able to upload a short 10-20 second video of the coral to show the flow they’re getting?

When I get home and the lights are on I will, starting to think It might be the overflow of the hobs , might need to add baffles
