I just saw this thread and I may have to do this. I have a 30 gallon tub with cured live rock in it. I could seed with pods and just keep it going. I'll have to heat it in the winter though. Would love to keep enough pods to keep my tank fed.
I took pods thru winter with water once hitting 48 degrees. I lost much more when float valve stuck, diluting salinity to 1.10 for a short time. Like I said, pods are durable. They don’t need to be pampered. When you try to maintain reef temperature with 1000G of water outdoors in the winter, it gets expensive. Yes, it’s true that higher temperature will excellarate pod growth. It’s your electric bill.
