Can someone please school me on the huge difference between a full apex and a jr. Other than an eb4 vs an eb8 and just a temp probe rather than the ph probe too. Thanks.

Apex full has I/O ports for switches, also has dual ph probes if you plan to do calcium reactor, as well as variable ports that can control DIY leds or pumps....
