So in a few weeks I will be finished stocking the tank for a while, which means I will not be using any quarantine tanks. I know that I need to kill off the bacteria in the QT filter media, and once that's done I should hang it on the display tank to seed it for the next time I need a QT.
The QT filters I'm using right now are an AquaClear 20 and an AquaClear 30, both are HOB
So here's my question. How the heck do I do this? I can't put these small HOBs on the display tank because it's a 150G tank and the glass is way too thick. I have a sump/refugium setup (I'll include a video of that below, I'm pretty sure nothing has changed) made up of a wet-dry filter box and a 20G-High tank. The HOBs would fit on the side of either of these tanks, but whenever the pump is running (basically always) the water levels of each of these tanks are so low that the pump's "arm" won't reach down to that level.

How should I deal with this?
