Hey everyone. Well I was doing my once every month partial water change and was wondering if I could refill the tank with a water hose. I have a 240 gallon tank and take out and replace about 75 gallons each time. I have been using a rubbermaid tub about 20 gallons at a time. I fill the tub and and water conditioner. I have a bad shoulder and don't look forward to it every month. If I am correct, Python users refill their tanks from the tap. How do they condition the water? Do they add conditioner before re-filling or after re-filling? What should I do if I use a garden hose. Also, because it's coming from a hose outside of my house, would 75 gallons of cold water effect my fish much? Thanks, The Doctor.
