Two apparatuses are disclosed for providing a dynamically varying water surge in a salt-water reef aquarium. When a user requests a network operation that will consume the network resource, an amount of the network resource to be consumed by the operation is predicted, if possible. The plate is exposed with a laser and on-press developed with ink andor fountain solution. Peak power handling capability of the fiber amplifiers is expanded by using optimized pulse shapes, as well as dispersively broadened pulses. In DMAD fluids, an aqueous slurry can have a solids phase including a degradable material and a fluid phase including a viscoelastic surfactant.
