260G, Alternate Bi-weekly:
* Sump filter change, WC Only~70%: Drain with closed loop connection/pump and refill with python: 1.25hrs
* Vacuum, wipe down, sump filter change & WC ~70%: Vacuum with python, drain additional if needed and refill with python: 3hrs
Aside from the time when I do vacuum the substrate, most of the time is consumed from pumping out water and refilling.
