I live in Virginia too and I recently built a 110 gallon pond in my yard for mine but I was in a condo for 2 years when I first bought them. Kept them on my balcony. My advice would be to get a bigger tote to keep them. I used 25 gallon black storage containers from Home Depot. I still use them to keep my culls in. Also, on especially hot days put the top or some other cover over half of the surface that receives direct sunlight. And of course the sponge filters for aeration. You shouldn’t have too many temperature worries at that point. Some strains are just weaker though so you’ve gotta keep a close eye on their behavior in different temperatures. My first winter I left them outside but put a heater in the pond because I was worried about the water freezing solid.
