I believe it's 116 GPH, or very close. Don't worry, the hose won't slip off! Also, you don't need to turn it upside down to prime, here's what I do: open all valves, disconnect the quick release on the pressure side, pull a siphon from the pressure side (into a bucket!) and once it starts quickly shut off one of the two valves on the pressure side that you just started the siphon from. Next, reconnect the quick release on the pressure side and make sure everything's hooked up and snug, then open the valve. It will pull a siphon and fill the canister. Once you can't hear it filling any more, plug it in and bada bing.
IMPORTANT NOTE: this is only required when the canister and hoses are completely empty. Just let it run for normal maintenance and water changes, given that it does not spray outside the tank. |
