Aquarium Advice Freak
i have a 120 gal tank. i just recieved 2 400 watt 20k mh bulbs my aquarium is really blue. will i still be able to have the same corals that i had when i had 15k bulbs last year. will i still grow coraline algea pretty quick.
i have 2 x 55 watt pc i was thinking of changing them to the sunlight color will that matter at all?
thanks
