Question on lighting please help

[Joker120]

hi all my question is I have a oceanic 120 tech tank. I’m running one radion g2 in the center witch is where 90% of my corals are. Now I have a green encrusting coral mounted rather high in the tank which is doing fantastic and spreading really good I also have a couple of frog Spons in different locations which are also doing quite well my question is it does not seem like anything is growing much they look great but not getting any bigger. I have a few leather coral that just do not seem to get any bigger or any new sprouts on them. I try to keep my calcium magnesium and alkalinity in check I’m not really big on water changes but I also only have about eight fish in the entire tank I’m running a eshpps protein skimmer and charcoal in a reactor with some filter pads that’s about all for the filter. My one light is about 9 inches off the waterline I was just wondering if the tank really needs more light. Please let me know what you all think

I’d look into one of those supplemental AquaticLife T5 retro kits everyone is raving about, in conjunction with your Radion. Then focus on water quality. Not sure where your nitrates and phosphates are at.
