Marco’s Rocks has begun distributing Key Largo Rock, We know what you’re thinking, quarried Florida Rock is very dense and about as attractive and interesting as a cinder block. Most of the lumpy Florida rock is quarried in mainland Florida, but Marco’s Key Largo rock is much younger limestone, and it more closely resembling the gnarly worm rock we all prefer for our tanks. We were amazed to find a two-handed piece of rock that would take up the better part of two feet of a reef yet it weighed only forty pounds. If that’s not enough, since the rock is made in the US and it doesnt incur nearly as much shipping expense, Marco is selling this beautiful foundation stone for about $2.50, and a typical order of Marco Largo Rock should still land for $3. Marco’s even has wholesale pricing for aquarium professionals who should also be able to sell the rock for close to that price. Check out the gallery below for the pictorial evidence of this fine new base rock from the Sunshine State.
