just started a 55 gallons acrylic tank, added tap water, sea salt (waited for it dissolve) then added live sand (40 pounds). i have a 1 1/2" bulk head fitting on the left upper side of the tank (for the drain). my out flow is about 12 to 15 inches away from the right side of the tank. my question is...... shouldn't it be in the right hand corner of the tank for better circulation??
