a picture of your lighting would help us out, at least a description of the bulb connection/end would help...
and you can probably try mushrooms or some zoanthids... go for green stuff or brown stuff, and of course cheap...
and ask those questions below/above... you are lookin for EASY stuff, as that usually means less light for most folks...
you can put together t5 lighting... you can gut your lighting system and install a new system in the hood/canopy...
you just need to buy the ballast and the end caps....
reflectors are nice and kinda important, and sometimes you can get reflectors and get them to fit into the stock hoods and sometimes you cant.. but as you can figure otu.. just do your best and constantly move into the right direction..
speaking of which, if you are concerned about flow... hows about gettting a new power head or two, or one at a time, and then later on, you can worry about the lighting, or the sump, and just do one thing at a time..
and speakin of sumps... they arent expensive either... you can buy a plain ten gallon or so tank form walmart and stick a pump in it, and pump it back to the tank, and get a an over flow for cheap from craigslist or ebay, and prolly for about $50 you are up and running
you can put baffles in it later on....
again, the point is to move forward step aat a time or it will be a big chunk of change not to mention a bigger shock to the system
