I've got a rio 400. First thing I did was remove the internal filter and replaced it with a canister filter. Next thing I did was buy a jager heater as my juwel one is faulty and currently being replaced.
Other than that though the tanks are great. They look good in a public area, mainly why I went with Juwel.
My sister on the other hand has a rio 240 and she's been running it for a month and a bit and she's cleaned the filter out once, and just rinsed some of the media. Hasn't replaced anything and her sterbai cory are still breeding so can't be too bad.
**EDIT** Oh as far as lighting goes my tank came with 2x nature and 2x day (juwel brand) when I have to replace the tubes though I'll be getting 2x colour instead of nature.
**EDIT2** Seeings you only have 2 tubes in your tank I'd go with 1x colour and 1x day. But you can probably find cheaper tubes from a hardware store or something.
