Do I need to prep my hose in anyway before siphoning for a water change?
Welcome to FishLore!
Do you mean like a garden hose? If so, I'd use a "fish only" hose (a hose that you dedicate only to the use of fish stuff). Otherwise, I'd run some hot water through it before the first use.
If it is brand new, I'd rinse it off really good.
I work at a yacht club so I borrowed an unused fresh water drinking hose solely for this purpose.
welcome to the forum
I agree, your fish hoses should be for the fish only.
I actually have specific hoses for draining and refilling.
Make sure you get as much water as you can out of the hose before putting it away.
