What would you do? - Tank Lighting Upgrade.

[wickedfrags]

Keeping 400's that close to the water could be a concern, when most people put their tank in a wall they usually have a little more hight to work with (as everything is hidden). 250's would also present a similar challenge, although not as bad as the 400W's.

You could indded keep SPS half way up and higher with the 2 x 250W, but should the SPS bug hit (which has been known to happen!), well many people want to upgrade to the 400's.

If I ran 2X250s.... couldn't I put SPS (eventually) half way up? I realize that coverage to the bottom wouldn't be great...
