Which Radion for a 20" deep tank? Part 2

[lyrical]

I had mine on a 6x2x2 and could grow Acro and clams on the sand bed no problem. I've actually seen them used on deep dimension tanks which are 27 deep and they work well.

That's really great info to know makes me feel a lot better about spending 2k on lights lol. Thanks a lot! :)
