Lighting for 225 gallon help

[TCseh]

I don’t speak freedom units but get the one that’s almost as big as your tank. You want to wrap your whole tank in light. I had the 150cm version on my 200cm tank previously. It grew acros fine even on the edges of the tank but I since upgraded to two 90cm fixtures and couldn’t be happier.

Eh…I’m sure they can at some sort of depth but 4-500 is more realistic in terms of how they will perform in our applications.
Honestly I can’t remember what the measurements where but I grow acros all throughout my tank.
I’ve been considering adding some kessils or something with narrow reflectors to strategically supplement the auroras at certain spots.

what the heck IS A KILOMETER. One lighting unit is 122cm, but my tank is 152 cm. Should I get the 149cm light?

It’s 1000 meters which is 100000 centimeters…see the logic haha

Yeah man, get the 149cm one (I actually think it’s 150cm). Both will work just fine but the larger fixture will be the better option both in terms of light coverage and overall esthetics (imo).
