I had a beautiful saltwater reef a few years back but due to relocation had to tear it down and sold most of my items. I currently have a 125 gallon tank in storage and would like to start up a freshwater setup. I had freshwater tanks as a kid and I am sure the technology has changed as I had those corner filters with an airpump. I still have the VHO ballast and wiring going into the canopy but I imagine this may be overkill for a freshwater tank as I don't plan on having a planted tank in the short term, long term yes but not short term so I am wondering if I should hold onto my Ice Cap 660 ballast and instead of running 2 72" VHO bulbs maybe run 2 36" T5 bulbs? Would this be a good starting point for a fish only now with a possible planted tank in the future? Also I am leaning towards a canister filter either the Eheim 2217-37 or the Filstar XPL I remember people liking the Eheims a few years back but not sure that is currently the case. Any suggestions or guidance would be greatly appreciated.
