Frogspawn and hammer coral looks unhealthy

[Supvnek]

Hey guys, I'm fairly new to the reef keeping hobby (~6 months into it). I have a Redsea Reefer 425 G2 and have a number of different types of fish and corals. Lately, I've noticed that my frogspawn (a green and orange) and my hammer coral look very unhappy. They used to be fully extended and nicely moving with the flow. I use 2 Reefwave 25s and have them running randomly at 70%. I'm attaching a couple photos and a video. My water parameters are as follows:
Salinity - 1.025
Calcium - 425
Alkalinity - 7.7
Magnesium - 1320

Any help or suggestions would be much appreciated

PS: I did lose a few acropora to RTN (I believe it's RTN since they were happy one day and they turned white overnight)

What are your nitrates and phosphate numbers? What par are they in? How much flow? They need low to moderate flow and 125 to 225 par

Bump the alk up a little bit, around that 8.2 mark

Alk is a little low- aim slowly to 8.5
Assure phos not elevated and coral not receiving excess flow. Same applies to light- Moderate -medium heavier in blue. While these corals are not picky about placement- best at mid tank or a little lower. Feed them Mysis - Not powdered foods. Mine are out of control with growth

Nitrate is 9 and Phosphate is 0.09...I've actually never measured par in my tank. I should probably do that to get a good sense.

I'm running my reef leds at 20,000K (100% blue and 50% white). My Phosphate is at 0.09 and Nitrate is at 9 (I think that should be fine). I haven't tried feeding them Mysis shrimp. I'll try that for sure. In terms of placement, Im attaching a photo and I've marked the locations.

Ok numbers are decent so focus moves to light and or flow problems.

Try 14,000K or reduce white to 35%

Yes that makes sense. My gyre is probably due for a cleaning. I'll do that and measure the par as well. That may be it. Thanks so much for the responses

Ok perfect. I'll give that a try and see how they respond. Thanks so much for the quick and detailed responses.
