Here is my setup.
Tank is still new at about 3 months and I am slowly tidying up the cabling and connections.
Tank is a shallow custom peninsula reef 60x36x14 inches approx 130 gallons.
Sump is approximately 50 gallons - 48x16x16.
Fish load is still low given the tank age, but will increase in time as I transfer my livestock from LA to SF.
Skimmer is DC180 with RD3 set at 37~38w.
Return is RD3 80w
2 Ecotech vectra M1. One for UV, and ARID reactor and one for seaswirl.
1 Abyzz 100 for main flow placed inside a korallenwelt dedicated rock.
Everything is connected to an Apex with 3 DOS and 2 DDR's for auto water changes and dosing.
Love the skimmer, I think it is one of the best investments one can make for their tank. The fine tuning provided by the RD3 and build quality are unmatched.
