Coral question

[Eoka]

I just wanted to get your thoughts on my slow coral growth and shriveled look. I just recently added a di filter which could have been the problem but I don't get much growth out of any of my corals. Could it just be the tank is to new? Or does it just take time. I have zoanthids that I've had for a year and I've gotten like 10 heads and I have other colonies that I've had for a couple months who only produce 1 head. I even have gsp which grows really slow its about the size of a baseball and I've had it for a year now.
Parameters
Kh-8.0
Calc-450
Mag-1200(haven't been dosing usally at 1500)
No3-3
Phos- 0.01
Ph- 8.5
Salinity- 1.025
Here's some pics of my hammer and alveo which I've seen extend before but there something wrong. The alveo act as a good warning sighn. I've had all my corals for a couple months or longer.

Off the top of my head... more magnesium, nitrates and phosphates.

I agree with @blaxsun. More mag nitrates and phosphates. Also, what is that growing all over your gravel? Is that cyano?

I've been told I could run them really low whats the problem with it

Yea I've had it off and on for a month

Your corals need nutrients, too. Letting them bottom out can lead to other issues.

I’m not sure where this ultra low nutrients thing came from.
I’ve had zero success with this thinking.
For years on end now, 10-15ppm nitrate and 0.1-.2ppm phosphate has really worked well.

I don't do it on purpose my nutrients just stay really low I don't even have that many corals

If your nitrate is 3ppm and phosphate 0.01ppm, Ty our starving corals slowly.

Any idea what your lighting is putting out par wise? Also on the ulns isn't a good way to go did that when the fad started in 2010ish time frame. Corals looked terrible to me they were way better in my 15-20ppm nitrate and .15ish po4 times. What size tank and how many/what kind of fish?

I'm using black box lights. My par in the bottom of the tank is around 100. I have a 125g with a foxface, copperband, forcep, 2 leopard wrasses, yellow coris, royal wrasse, 2 clowns, mandarin dragonet

Pretty good amount of fish maybe up food some or if skimming maybe cut it off for a few hours a day. Do you have a fuge with macros?
I had to fight really hard to get my levels to where yours are back then, even now I struggle. I don't get it. Currently I just have a 30g with an angler I feed once a week. I feed corals maybe every 2 weeks lightly with mysis or a pellet or two maybe once a month I broadcast feed a light amount of reef roids. My nitrate is 10-20 and my phosphate is .03-.08. I change water once a week about 7g. Which I do to achieve a roughly 100% monthly wc.
Everything in my tank looks healthy and is growing so I'm not complaining.

Yea I have a refugium. I started doing daily feeding with ab+ and notice that my alveos aren't closed up so maybe that's the problem.
