Hi guys, I have what might be a silly question, I have two aquariums side by side. I was wondering if I use two water pumps that are exactly the same (which I have) will I still need to heat BOTH aquariums, also would this even work in terms of water transfer? asking this as my second tank is unheated and only has a few plants in at the moment, I don't want to go to the expense of getting a heater and a new co2 set up for the second tank so was hoping I could use a simple transfer system like this?
