hey everyone, I just have a quick question. i am considering "upgrading" my tank from a 20 gal
to a 29 gal
if i use a gravel vac to move the water from 1 tank to the other, and if i bag up the substrate under water, move it to the other tank and release it under water, and then switch the HOB
filter over (yes it's enough gph
filter) would i have to worry about the nitrogen cycle? or should i be ok?
