Hi i have a 4x2x 2,5 height fish tank, using 2 blue 2 white T5 lights. When I on them all, the effect is rather yellow white effect. However I have seen smaller tanks like 2 or 1.5 height using 2 blue 2 white T5, it was rather shiny blue effect. Why is there differences? Could it be the height diff or the brand of lights? I am using only hopar t5 lights fyi. Any advise is appreciated.
Thanks.
