advice for my new set-up

[fencer]

APEX get one
Need a calcium reactor
Need an RO/DI unit
Ken has those next reef media reactors much better than the smaller phosban'....all I run is GFO and Carbon
ATO...nice but do you trust them
Save the dosers for later
Stay away for now from ion selective probes buy a couple of elos or salifert kits
Chiller and UV do not have one
