I'm completely new to this hobby and have a newbie question. The search function isn't working for me right now and I've been reading forums for days looking for this, but I guess I gotta ask. Can anyone give me a run through on water changes? What is your personal technique? I don't have an RO water filter yet, so I planned on getting distilled water from the store. What do you mix your water in? I have a 55 gallon tank and plan on doing 10 gallon water changes. Do I need to find a 10 gallon container, mix the water/slat content to my tanks specific gravcity and put a small heater into the container to match my tanks temp? Then drain the 10 gallons from my tank and add the new water?
