I'm setting up a 20G tank. Going to be FO. I have a Aquaclear 20 powerfilter and an Aquaclear 30 Powerhead. Going to get some rock that is white, but looks like red lava rock because I just don't have the money for LR right now. About 30lbs of aragonite sand. I have a 100W heater for it. Will this be sufficient enough to run a successful tank or does anyone have any other recommendations?
