I run 2 HOB
's on my 90 just so i have 1 for the QT you wont need a PH in the tote with the hob
it will move enough water, just the hob
a heater and a place for the fish to hide no need to spend a lot for the QT.
when your done with the QT clean the HOB
refill with poly-fill and put it back on the DT to build a new BB for next time
