hi i am new to mfk and am in the process of setting up a 75/90 (48" x 18" base) central american ciclid aquarium. i just bought a sedona aquarium stand and canopy. i have polished concrete floors. my quesion is the stand is not perfectly level: it's about an 1/8th inch from from being level from front to back on the right side of the stand (ie i guess my floor dips a touch in the front right corner of the stand). what is the right approach to getting the stand surface to be level before adding the tank and 600-700 pounds of aquaria? thanks for any helpful feedback in advance. mike
