Okay, like the title states, I'm not a newbie, but this question kinda is! I've got quite a few tanks, but now the girlfriend wants one of her own...its just a 10 gallon but she loves it. My question is...HOW can I cycle it at my house (she started college soccer 2-a-days doesnt have time to test water/change water etc) and then transport it to hers? Obviously drain most water out before I take it over to her house...but how much do I need to leave in there so it doesn't mini-cycle when I fill it back up...? Thanks everyone!
