I plan on setting up a new tank in a few months, and wanted to go ahead and begin cycling my rock. I have a large cooler that it would all fit in, can I just put the rock in there with a circulating pump and a raw shrimp and let it go? I live in Florida so would it be too hot to let sit outside? I realize that warm water holds less oxygen, but maybe place an aerator in the tank as well to ensure the growth of beneficial bacteria? Thanks for your help!
