You can, but it means switching out the bulb socket in the unit as well, since 250w DE is larger than 150w DE. I know a couple of members who've done it. You may also need to switch to a more powerful fan.

For your needs, medhat, the 150w should be fine. See how the carpet does under it and if you need to, J&L does sell Geisemann bulbs, but not sure what k? I grew clams, anemones & LPS under my 150w in a 2' deep tank for years before upgrading to 250w.
