Nyos opus 300

[Tuaregy]

Hello all,
I could use some help with my tank if possible. Tank is Nyos opus 300 dimensions are L x W x H 35,4 x 21,7 x 20,9. My equipment is as follows:
2x radion xr15 blue g5 on radion mounts
3x vortech mp 10
1x vectra s2
1x clarisea sk3000
1x nyos skimmer 120
For lighting I run ab+ at 70% intensity.
Water parameters are:
Po4...0.08
No3...2.6
Dkh...6.9
Mag...1320
Cal....420
Salinity... 1.024-1025
For salt I'm using TM pro reef.
I dose korallenzucht amino and coral vitalizer, both every 2 days ( as instructed).
Tank is one year old.
So with all that said I have problems with my acros. Green slimer has almost bleached same strawberry shortcake. I also have bali tricolor witch is growing fine, a bit slow but colors are there and polips are out so does milka. Montiporas are also growing, slow but steady. One sps has turn brown a while ago but it's getting green color back ( tho it looks the same for 3 months now without any change). Space invader chalice is not growing at all, it has that vibrant color but it's not going anywhere.
Basically corals are not looking so great. I could use some advice what to do to because I'm lost here.
Any suggestions is appreciated.
Tnx

Your lighting is comparable to what I run on my tank, so other than tweaking the spectrum slightly I don't necessarily see any complete remedy there (check the index page of my build link for my Radion template).

In terms of parameters, I think they're a tad low. I'd aim for 8.25 dKH, 450 calcium and 1450 magnesium. I have my salinity a bit higher at 35.5ppt as well. I use the same salt.

My SPS grows like a weed - but this is just my tank (YMMV).

Hi, I just looked at your setup, thumbs up for the post. Is that setup for xr15 or xr30 at 75% intensity?

Did you have to modify sump to fit clarisea fleece roller and skimmer both?
