[Aaronsreef]

Currently I have the water box 110.4 it’s 120 cm long and 50 cm wide and about 50-55cm deep

Currently useing 2xr15 pros (ab+ setting)
Bubble mag curve 5
2x max spec gyre 4k (at 75%) on Radom
Tmc 4000 return up
Clarisea sk3000
Useing about 100g of rowa in a reactor

Numbers don’t seem bad in my icp tests all in the green

0.05 po4
25 nitrate
440 cal
1300 mag
8.0 kh
8.1 ph (run out of ingredients to test again )

1.025 salt
Temp 25.3

All tested with Hannah tester (last night)

All pretty stable few p04 spikes 0.07 to 0.04 (but that could be Hannah)

10% weekly water change

I’m really struggling with SPS even the “easy” types.. I’m thinking maybe lighting ???? Should I add one more xr15 pro ??

Any ideas or any different equipment what will help !?

Cheers in advance currently at work ill reply when can

Most likely it's the PAR output from the 2 x XR15s. I run 3 x XR15s on a similar sized tank (although a bit deeper!) at 75% output and this is my PAR readings.

Do you have access to a PAR meter from your local fish shop?

I’m thinking of adding 2 reef brites to add some and maybe one more xr15
