i have about 90 lbs of live rock, maybe more. it fills up the 75 gal
tank, maybe a little too much. im having issues on how and where to place the rock. some are about the size of a football, very large and very heavy. some are like a tree branching with the braches very close together. and one has a long oval shape plate, about 14 inches by 9 inches. i think the plate shape has the most coraline and color on it, more like a center show piece.
but i have trouble on how to do this and what is best for my tank. should i stack them up like a mountain. or have one set on each corner and have little in the middle. do i place them up against the back wall of the aquarium or right down the middle. i want what is best for circulation and health of the tank and rock. by the way, what happens if the rock with coraline is under and shaded byt a rock above. will the coraline die off because of little or no light. i have look as some pics in the gallery. they are great but i wish to have more of a 3 dimensional or a layout from the top of the tank.
