so what's that, around $457 ... give or take .... ouch ... from what I've learned now, aquarium gravel is not your friend ... use pea gravel, river rock or quartz sand ... save money!!
most expenive thing was obviously the filter, and the lights ... but the filter as long as it's not leaking works really well ... the lights are actually burned out already, and I've since upgraded to power-compact ... which was well, another $100 roughly!
