Light Change Fluval>AI Blades

[dbaulch83]

Hiya,
Moving from a single Fluval Sea LED light to 2 AI blades glow and grow. Have nems (which seem to prefer the Fluval light down at around 30%?!?), and a torch coral. My aim is to expand the repertoire of corals but be kind to what’s in there. Tank is 50cm deep and the new lights stretch across the entire width but will also sit a good 10-15cm above the tank surface whereas the old light was closer to only 5cm.
Appreciate it will be difficult to offer bespoke advice here without PARs but some general good practice at light switch over would also be welcomed - also AI settings advice
Many thanks

I have a single 30 inch one in my 32 inch long tank. Its pretty bright alone and thats all I am using. I am barely using 16 watts of it and reaches the full 81 cm tank depth. Granted, I have it sitting on the tanks rims but you honestly should be good.
