Im setting up a 75 gallon seahorse tank with a lot of macro algaes and I was thinking about doing a t5 fixture. Is this a good idea if I was to do like 3
6500k and 3 blue actinic(so the colors look good)?
That is fine. I'd suggest Blue+ from ATI, also 6 bulbs may be a little intense. The more 6500's you have the browner and yellower everything will look. I'm using 2 Aquablue (12000k), 2 Blue+, and a Fiji Purple with pretty nice growth over my 100g. Keep in mind plants use blue spectrum to photosynthesize so blue bulbs help growth as well.
Try a couple of 6500's and mix some 10k bulbs and blue/actinic for a nice look. I don't like the look of even one 6500 added to that mix I have because it's so yellow. I have two GE daylights sitting unused next to my tank in favor of cooler bulbs.
Mix and match to see what you like. I think you'll probably end up sticking with just one 6500 because you'll see all the others have to balance it out to provide a more pleasing look.
Well I ended up on BRS and seen a nice fixture with either 4 or 8 bulbs..Im thinking about ging with the 4 b/c you get 25% off bulbs and that sounds like a good deal. I have some nice flame algae and another red one that is in my refug waiting to go to the seahorse tank but i got to figure out lights first. So Im thinking maybe a little less lighting so i dont make them turn brown?
Okay so Im going to go with the fixture from BRS and get the bulbs since they are 25% off when you get the fixture but Im not sure what 4 will be the best choice. I was thinking of 2 6k's, actinic plus then another blue of some kind. Does this sound like a good idea? The tank is in the living room so I dont want to much blue so thats why I was thinking 2 6k's.
