Hi all, I'm new to the forum and things have changed quite a bit since I last housed any salt tanks. I currently have a 40 gallon fish and softie tank, but I'm looking to upgrade. I am looking at a 115 gallon with overflows and I'm in need of a sump which leads to my question: should I go with a refugium or stick with what I know which is wet/dry? Any thoughts and concerns are greatly appreciated and I would really like input on where to find good used equipment as I'm trying to upgrade on a budget. Craigslist has been helpful, but it seems rather sparse for equipment. I have lights (old school as well... metal halides) but am looking for sump/filter, return pump, skimmer, heater, etc. The tank I have now started out as a gift for the kids, but I've become addicted and need more room. I want to make it a reef tank for sps, lps, and fish. Again, any help and input is greatly appreciated.
