I have a 72 gallon bow front. Fish and coral. I just got a 4 bulb t5 set up. Should I keep the bulbs that came with it (2 white/2actinic) or should I change it up?
i would go ati 3 blue + and a purple. if you like it a little whiter you could do coral + instead of the purple. id see if anyone has some old ati bulbs laying around they could let you have or borrow so you can play with the color combo and see what you like before purchasing.
