For a 110 with that setup, the stuff I'd expect on a standard weekly visit:
- review the Trident and NP logs
- spot-check alk/cal/mag with a hand kit so you know the probes haven't drifted
- top off the ATO and refill the doser containers,
- nudge doser rates to whatever consumption's been running,
- clean the skimmer cup and neck,
- swap the filter socks,
- wipe the glass, and a
- general once-over for anything off.
- A water change usually rides along too, though plenty of services do 10-15% every other week rather than weekly.
What I'd treat as beyond a routine weekly — and worth pinning down in writing before you start — is the deeper stuff: probe/Trident calibration, pump and powerhead teardowns, RODI filter and membrane swaps, GFO changes when it's spent, and anything event-driven like a cyano or dino outbreak, dips, or coral work. That tends to be as-needed or add-on, not baked into the weekly rate. I'd get it itemized either way — "weekly maintenance" means pretty different things shop to shop.
