Hi guys. Just got an used apex el 2019 $300 (can't pass). Never have Neptune system before... please share tips n tricks. My system so simple... most of them by Ecotech ( lights, return pumps and power heads) now control by Mobius. Two parts dosing and Arco power control by Bubble magus dosing pumps, i do have skimmed but they run 24/7, i have refugium light run opposite time with my lights control by timer. Could you please teach me best way to utilize all equipments. TIA
