I recently finished my cycle of my 75 gallon saltwater tank. I used a wet/dry filter to start the cycle. My reasoning for this was because of the fact I used mainly Lace Rock for my setup and just a small amount of live rock. I figured it would get the cycle going quicker. It may have been a stupid idea but its too late now.
Well my cycle is done and I added 2 clowns and a small cleanup crew. Everyone is doing great, and other than some algae/diatom issues all my parameters are fine with nitrate only being around 10ppm. I'm not that concerned about having bioballs because I do a lot of maintenance on my tanks on a daily basis so I dont forsee having a nitrate problem in future.
I do however, want to setup a refugium but have no more room because of my wet/dry filter takes up almost the whole cabinet. If I were to remove the bioballs and go with a sump/refugium, would it be ok to remove the bioballs all at once? I do have about 150 lbs of rock in the tank right now and such a light bioload. I know its recommended to slowly remove them and if so that what I will do. I just thought maybe having so much rock that a lot of the bacteria would be colonizing that as well.
I would slowly remove them only because of it being a new tank. If it was well established esp. with that much LR I would say just take them all out but being a new tank let`s err on the side of being safe.

Thanks guys. Hate to be a pain but I was thinking of another way but not sure it would work. What if I set up my new sump and put the bioballs in my middle refugium area and slowly remove them in time. Skimmer would be in first section. Once they are gone I could start my refugium. They would basically be submerged now so I'm not sure if it would work.
