Sps corals under t5's?

[sahin]

Start the new coral at the bottom of the tank and slowly move it up the rockwork over a couple of weeks.

are you saying the 12 is the same as having a 6bulb in other fixtures?

yes kissman, my 12 bulb fixture is 6 bulbs front to back, six on the left and six on the right. So it is basically the equivalent of a 6 bulb fixture.

Now i understand. I thought you were saying the NEP puts out half the light as other HO T5 fixtures. I have a Nova Extreme Pro that has 6 48" 54w ATI Bulbs.

do power heads need to be facing the coral and be blowing directly on it or can it be indirect, and can too much flow be bad for acroporas?

You want strong indirect flow around the coral. Look and see if the polyps are moving a good amount and you are fine. Acropora do not appreciate direct blasting flow constantly on it.

With 4 bulbs, I would stick to birds nest and monti' on the 75.

It's hard to tell; I think it could be a Birdsnest, but it could also be a Stylophora. It needs to grow a bit more to be ID'ed more easily. Just my 2 cents.

As far as your lighting question goes, yes, I believe you should have no problems with good and stable water parameters and strong, indirect flow.

If that Tenius was brown at the LFS, then I'd say you're doing something right. :thumbsup:

 

[Mattchamp]

It was brown at the store, and thanks

 

[Mattchamp]

It actually has a slight purplish tint to it but the camera doesn't catch it

 

[kaserpick]

Well, it looks like it's doing well. Like I've said before, as well as others, I believe you'll be fine with your current lighting. At the very least, you should be able to have SPS thrive, in both color and growth, in the top half of the tank.

 

[Mattchamp]

oh and the acro has white tips is this a sign of bleaching or growth? and it is only the top most polyp that has turned white.

Is t5's strong for acros and should they keep their colour?
