I have a 30 gal sw tank that has been set up for several years. Actually, it's been up for over 20 years, only the last 4 of which it was under my care. The tank relies on older technology (ugf, crushed coral substrate & mostly decorated w/ pieces of dead coral and *maybe* 3 pounds of lr, and NO protein skimmer) but it has done great despite this. Its current occupants are all thriving (2 fish, 2 shrimp, 3 urchins) and I'm sort of thinking that if it isn't broken, don't fix it. However, I've been considering adding a small amount of additional live rock because the tank looks pretty boring, especially compared to my reef tank. If I did this, I would add the live rock just a little at a time. What do you think? Should I try it, or just leave well enough alone?

No problems with this. Add about 5 pounds at a time. Keep in mind that with a UGF you will need to get at the plates to keep them clean, so don't cover the whole bottom. Many will say remove the UGF, but I say leave it. It's working, and there are no problems with using them.

Great! Thanks for your help. I'll be getting some lr next week when I go down to FL.
