That might be difficult to do, I'm not very flexible...



The sump was initially sized and intended for a 90g fish-only freshwater tank. I decided to make do with it until I needed to change it up. I hesitated including the bio-balls initially but decided it may make denitrifying easier in the short term (start-up).

I think what I’ll do is just put them in a bucket of tank water, do a water change, install the new sump, and then put the balls into the refugium chamber for a while until I’m confident the tank won’t cycle.
