Frag tank

[phi delt reefer]

may want to swap the uvl actinic for the ATI Purple plus or KZ fiji equivalent or at least pickup that bulb as well to give you some options as you dial in the color.

thats the great thing about a 6 bulb or more unit. Easier to dial in the perfect color. 4 bulbs limits your bulb choice but there are PLENTY of amazing 4 bulb tanks so its going to be up to you to work with what you like. color is a personal thing but all of those bulbs have good par so growth shouldnt be an issue.

Will the light spill over on a 6 bulb unit be much of an issue with the tank being 12 inches? If not I would just go with the 6 bulb to give me more options

too much spillover with a 6 bulb unit - u'll just be wasting light. I think somebody just listed a 5 bulb aquatanics tx5 unit in calgary for 200 a few minutes ago. they are pretty good fixutres and the 5 bulbs open some combo possiblities.

So long as you feed the frag tank with clean water (downstream from the filter socks etc) it should be a fairly maintenance free tank as well.
