Having just set up the 750g in Sept, and starting with (12) G6 Pros, (1) Panta Rhei ECM63 and (2) Abyzz Flow Canons 150. I can say that upgrades aren't needed for awhile.
All our equipment is located on an exterior wall of the house, and we have the (2) 180g outdoor frag tanks outside in direct sunlight.
While we don't have anything to upgrade, since we had such a rainy season this past winter there is lots of stuff that got 'washed' that needs to be replaced (mostly Apex modules). And a bunch of crap that just needs general clean up.
Our filter wall which was so fresh and clean a few years ago, doesn't look so great and looks like a wire nightmare after upgrading float switches, replacing skimmer pumps, updating to a 4k RO/DI System, a 340glass sump blowing out, upgrading the upper tank the skimmer sits in, the UV on the wall self destructing and leaking on everything below it - etc etc. We are in the midst of retiling our downstairs, so all the crap on the side of the house is my excuse, now that nice weather is here, for not getting into cleaning up the outside equipment. Everything works really well and other than swapping an Existing 220v 2500w Titanium Immersion heater with a 4500w 220v Bigger badder version, the rest is just clean and swap.
These are photos when we built the wall in Aug of 2018. I'm not willing to show what it looks like today - LOL
