Dumb question.. and maybe this applies to other no-name import canisters as well:
When you pop the top off the canister for a media change, what prevents water from continuously siphoning out of the suction and discharge hoses? I realize you'll get some spillage just from unlatching and removing the top, but I don't recall if the hose connection manifold deal on the canister top had any type of check valves or shut-offs in it?
If you undo and pull the hose manifold off the top, does that shut-off and prevent back-flow of the water? Directions and/or literature were basically non-existent with this ~$50 unit (as expected).
Thanks.
