I have a large goldfish tank (240L) and I am going to be going abroad for around 4 weeks. I set up auto feeders already, reducing feeds to once every two days and turning off heaters in order to reduce appetite. I am also planning on seeing if I can set up something to automatically perform a 50% water change after 2 weeks. I set up a submersible pump in the tank connected to a smart plug to pull water out and another one feeding back into the tank from a large 150L container but I was wondering how I was going to condition the water. If I fill the 150L container with tap water and use Seachem prime will it be fine to sit in the container for 2 weeks before going into the tank?
