Im not familiar with the ASM line of skimmers, but if theres a chance that a bigger skimmer would be more appropriate in the future, i would just get it now. looks like you are going all out.
The skimmer is probably the single most important item next to lighting. if youre spending good money on the entire system (calc reactor, wave maker, chiller, digital monitors, etc.) oversize the skimmer and get a top brand.
