Hi all, as I am new to the hobby, and about to start out, I wanted to get some information regarding water changes. How is this achieved without disturbing the substrate and plants especially If using products such as ADA Aqua Soil. I have read somewhere that you must not use a gravel cleaner in these aquarium set ups. Also what temperature must the water be? Can I use cold tap water from a garden hose pipe or do I need to a mixture of cold and hot water from a kettle?
Cheers.
