Too Much?

[CandyCane]

Hey guys so im doing a 20 gallon nano, standard tank, and wanted to know if this was to much light. Im planning on suspending it but im not sure. I want to keep a hammer and a torch with a GBTA and a maroon clown. I may in future want a few other SPS or LPS corals but I cant see myself getting any hard corals for this tank.

this is the light its a 150w HQI with two t5 actinics for a total of 174w
