I have a 40 gallon sump with bio balls. I am replacing it with a sump/refuge with bio balls for my FOWLR. I have 150 lbs. of live rock in my 125. The new sump only holds about half of the bio balls as the current sump. My question is should I remove bio balls now until I get to the capacity of the new sump, or can I make the switch and reduce the bio balls by half? Thanks for your respones.
