Fintique sells an attachment that fits onto a water faucet and a garden hose (I think there is an attachment for a kitchen faucet), there are two settings, one will draw water out of the tank and the other will put it in. Works well for my freshwater IMHO and would do ok for drawing out water of salt water but for obvious reasons would not work putting waterback in :lol: you'd have to be very careful with saltwater tanks.
