new to hobby filter conversion?

[dabandit]

Get one of those overflows where the tank doesnt need to be drilled and run a sump. I used to run a conversion full of live rock,carbon and phosphate media it worked as well if not better than my phosbans but it needs to be cleaned every week. Dont fear the sump a properlly designed system cant possiblly fail,worse case scenario you might burn out a pump.
