Slow Coral Growth

[ItsNotAboutOil]

Hi Everyone

Looking for some advise. I'm really struggling with any noticeable coral growth. i have mixture of Soft, LPS and SPS. i have noticed with my LPS frags seems to have number of heads not much of a skeletal structure. Tank is 18 Months Cade S2 1500. ICP results below - https://www.triton-lab.de/en/showroom/icp-oes/176497

What kind of lighting and flow do you have?
A Tank pic always helps visualize the issue's.
