I am new to the hobby and have just set up a 30cm square low tech tank. The tank at the moment is a plants only tank but that may change in the future. The tank as I said, is low tech with no filter, heater or light. I completed the planting last Tuesday 21st May. No liquid fertilizer/CO2 has been added yet. Please can someone recommend how long I should leave the tank to settle before I make a water change and what percentage of water should I remove?
