Its depends on what you want to have in the tank. Lets take a look at what you could do.
If you have 3 175 w then you are going to have to have actinics to go with the lighting more money!!!
If you have 250w you could get 2 x 250 with 20K and you have fixed the actinic problem , I would have 2x 250 w with the 20K and have a set of 40 w actinic for morning and night viewing.
no i dont know why people would go to have 3 MH where you could have 2 Mh over a 6' tank.
man i had a 400w 14 K over a 280 gal tank with my softies. It's all going to depend on what you wold like to have.
And i have also have had a 400w 6500k over my tank with 4 NO actinic
The guy would can handle this question is Doug ,Soug has had many options over many tanks. But dont get me wrong there are many peole here that have had many options on their reef tanks.
Any way there are lots or people that will try many ways on making this a cheap hobby. But that nevers happens
