Looking good and welcome to TR. You have come to the right place to help you get started right. The only suggestions I would have for you is since it is an old
FW tank make sure there isn't any
copper residue left over from meds etc that may have been used in the tank. Also for myself I would skip the carbon/sponge filter (These may cause
nitrate problems down the road) and look into getting as much
LR as you can in your
sump. Just my opinions like all of the other advice you have probably gotten so far.
