How do I connect a pump to multiple tanks?

[Oddible]

In the 4th scenario I started with one that was connected to two tanks but I moved it and now I can't get it back connected.

If you select the pump, in the upper section of its info panel, it will state which tanks it is connected to. If you place it, you can already select a single tank. If you look at its info-panel, you'll see it. The little icon next to it will be empty though, and that's the second tank.

To connect it, select the empty icon, then select a tank.


And to your previous question:

The system is identical to that of the coldwater tank. It's just that you need chillers.


If you have a tank and you want to heat it, you put a heater next to it. If it's a big tank, more heaters are required. It's not a matter of "how hot does my tank need to be?", it's a matter of "hot enough". And it's hot enough when the fishes inside don't complain.

Same goes for a tank and you want to heat it. You put a chiller next to it, more if it's a big tank. It's cool enough when the fishes inside don't complain.

Interact with those two panels and you can connect your tanks to a pump.
