i took out most of the gravel in the tank. its much easier to clean, now i dont have to syphon the gravel in haste trying to get all of it done b4 i reach my max water change. otherwise i dont have water to replace the tank water that i drained cuz i was too busy syphoning gravel. definitely taking that idea into account that marble tiling setup, and use it on all my other tanks, very nice looking but very efficient to clean. i hate tank cleaning when its too much to do.
