My nitrates have gone up from pretty much zero to around 5 or so in the last week or two. I guess it's probably time to get rid of the bio-balls but I'm assuming I shouldn't just remove them all at once. I'm reading and trying to figure out how I want to build my fuge. I changed from cc
to a DSB
several weeks ago and have around 120lbs LR
and another 40 or so of base rock so should I just remove like 1/4 of my bio balls every week or what?
