Thanks for the tips, but although the tank is new, I had a 140 gallon setup 25 years ago that ran like a charm. I'm not new to saltwater, just to these newfangled filtering systems. As I mentioned in another thread I started, the store I bought this at (the only show in town, evidently) only sells fake and live corals, no natural dead coral, hence the fake stuff. I'm not too thrilled with their knowledge base so I found this board. Believe me I'm doing a lot of reading up. I plan on putting some LR and LS this weekend, just waiting for the water to clear up (and for this ice storm to pass!).
btw, where on this site can I read up on the abbreviations you guys use? I figured out LR and LS, and LFS, but there's a ton more that's over my head.
