I would like more info on how the cliffs were made? Also what lighting and filter are you going with. Never seen a 120P set up this way. probably end up with 40 gallons of water instead of the 70 gallons the ADA 120P normally holds. Looks great BTW
The cliffs were made with eggcrate, spray foam and then covered with exo terra plantation soil. I dont even know what brand the light is, i bought it all together but i cant see any brand in the light. Yeah might be even less than that, im only planning on filling it up with about 6 inches of water.
