i have a 210 gallon tank 6' long. i just got a current light fixture with 3x 175 m/h and it has a few led for lunar but you can only see them at night. the tank now is too yellowish i want to add some blue, can i just change the m/h bulbs? or is there a small light fixture i can add for some blue light. i dont have a canopy so i am trying to keep it nice and neat. the current light fixture is only 8" wide so i can open the glass on the top of the tank to feed the fifh.
