I recently moved a 125 gal tank into my basement. I hope to have a sink put down there soon so that I can use my python (actually a store brand version) to change water. Until that time there is no way the 50' of hose that it came with the python will reach from my kichen sink to the basement. So, if I buy a 75' garden hose can I use that to fill my tank? I'm only concerned because I've heard that garden hoses can contain lead (and who knows what else). I just don't want to poison my fish. I plan to use a hose and a pump to remove water from the tank. Thanks for any advice.
