I've got to fill and dump with city water one more time before filling with RO water and starting to cycle it late next week. Hopefully tomorrow (Monday), more of the fish will show up for the quar. area (3 silver aros, 2 black pacu and a RTC).
The arapaima pool is drained waiting for the contractor to fix some issues with design that I pointed out. Once they are addressed, I'll dump and fill with city water three times, then fill with RO and start that cycle as well.
As for now, I'm daily netting out leaves and misc debris. I backwash the sand filter every other day or so, just to keep them clean while the calcuim and other minerals leech out of the rock work. I'd hate to have to replace a filter before the fish hit the exhibit!
