Let me start by saying I think this site is the best on the web for information and suggestions. Also, I am NOT any kind of expert in this field. I started about 18 months ago with a 55 gallon and was given (eat you hearts out) a 65 gallon (complete) about 6 months ago. I set up my 55 using only 2 Marineland Emperor Bio Wheel filters, 2 power heads a heater and good lights. That's all. I slowly added live rock and some Damsels (OK, that was a mistake. Now I can't catch them to get them out and they are aggressive.) and some coral frags. I've since added a few more fish and corals. I wanted to focus on corals so the fish were sort of secondary. I do water changes irregularly with tap water (from our well) about every 6 to 8 weeks and top off with tap water, The tank is doing GREAT. The corals have grown to the point where I may need to "crop" them. The only problem I have had (recently) is some bubble algae developing. I haven't lost any fish or corals and this set up makes me think simpler is better. I'm not saying this will work for everyone but it sure is working for me. It leads me to believe you don't need all the expensive gear to have a nice tank. Now for the 65 gallon. It was given to me with everything, overflow sump pump, skimmer, etc. (even the "moon lights"). I replaced the powerheads which weren't working very well (2) and added a Bio Wheel filter as well. The guy who gave it to me spent thousands on it and even had a maintenance guy service it bi-weekly. Nothing was thriving but a nice tank overall. I've had a problem with Aiptasia (came with the tank) and a bit of hair algae but nothing serious. I'm doing the same "maintenance" on this tank and things are doing a lot better, corals are growing well. I guess my point is that I see little difference between the 55 gallon "cheapo" tank and the 65 gallon. I may just be lucky but after more than a year I think things have pretty much proven themselves out. It seems to me that good water flow, lots of filtration and careful feeding will give you a great tank regardless of the expense. Again, I don't consider myself an expert and I love to read all the forums and advice and have learned a lot from this site. But don't be afraid to experiment a bit and try things out. Technology isn't always the answer. Pictures attached.
