If you can read all five items on this key, you did not buy this hoodie, you earned it. FIG. 1 is a clean mid-century cutaway of a working saltwater reef tank system: display tank up top, sump and skimmer below, every part called out in a numbered legend. And item 5? Any reefer already knows why the alk swing is not shown.
Soft brushed fleece, cozy from the first wear, with a hood for water-change mornings. A quiet flex for the reef keeper in your life: a build-completion marker, a tank-anniversary gift, or the hoodie they wear to the next frag swap. Drafted like the manual. Worn like a badge.
