we have another store in town that deals with saltwater. should they need something we don't have, they can always go there.
this is my point exactly. You may end up actually loosing customers over this. They try
SW, decide they like it...now they want bigger tanks, more equipment, different fish, lighting, corals, anemones, invert...the list goes on. Your store can not currently support this need. They will be forced to go to the competition and while they are there, they might as well up up the
FW supplies they need as well. Bye-bye customer.
