I started in this hobby about 6 months ago and have my AIO Aquatop 24 gallon up and running great. So now I want more haha. I want to go to a tank where I can do a bigger reef and have tangs, snowflake ell and just room for some bigger fish and more fish as well as coral. So I started looking around and I see the redsea tanks like the 108 gallon tank, I think this would be a great size for what I want to do and it comes with everything but a skimmer for $3,200 which seems high to me. The biggest problem I have is that my AIO 24 that I have I bought it then had to pretty much change out everything it came with to make the tank stable and good. I changed the light, the filters the return pump so its not even the same tank anymore and I really just bought the glass and the stand. So I need some help here, going into this upgrade to a 100 plus gallon tank if I was to go with the red sea AIO is that a good setup? Would I also need to upgrade everything? Would it be cheaper to part together a tank, if so what would be the best way to part together one? Just any advice or feedback would be great. Thanks for the help.
