could anyone give me some setting suggestions for shooting my tank. i have a nikon d90 with tamron18-270 mm. not real good at this at all. thanks in advance everyone and ill post my pics.
 
Read the sticky on image posting and shooting. That lens isn't a true macro either.
 
There's really no one size fits all answer we can give you. There are too many variables. . .tank size, distance from which you'll be shooting, tank lighting, type of shot (full tank, macro, etc.), composition, and probably a few others I'm not thinking about at the moment. I'm not sure what your proficiency is with photography in general, but if you're new to SLR photography, I'd suggest picking up a book like Understanding Exposure, by Bryan Peterson. But just to illustrate what I mean, here are the range of settings I'd consider pretty typical of my aquarium photography. . .

Aperture: f/5.6 to f/22
Shutter Speed: 1/250 to 5s
ISO: 100 to 1600
Focal Length: 28 to 100mm

It just depends. . .
 
As stated, it really depends. Are you shooting moving fish or stationary coral? Really there are no settings that will universally work. Your glass may be thicker, light may be brighter, etc....

Definitely do some reading on DSLR settings, it all applies here.

Basically it's all a balance of the 3 main settings, shutter, aperture, iso.

You usually use the slowest shutter speed you can use without blurring due to less light reaching the lens on a reef tank.
Use the aperture to adjust the depth of field to an acceptable range. Larger aperture number means greater depth of field, but less light reaching the lens.
ISO is like a last resort to boost lighting, but it also adds noise.

Shooting a moving fish would require a higher shutter speed, then balancing the aperture and ISO to get a decent image without blurring.

Shooting a coral with a macro lens would likely be shot with a slow shutter speed on a tripod, adjusting the aperture to get a decent in focus range, then adjusting iso to set the brightness. You may have to lower the aperture to get a result without noise in some instances.

Read some general photography tutorials, you'll get it.
