Great thread idea.
I do start with an old school softy tank picture.
2x400 Phoenix 14k, Dsb, GFO, Ca/Alk/Mg dosing combined with Kalkwasserreactor, Reefkeeper lite and Evaporation cooling.
The system is running on 2 MAG pumps in which one is Battery backed up and some Koralia 1400 supported by 1 MP40.
Aqua EV skimmer and algae filter is used as well.
The sump has a 3inch layer of Fijimud.
