Aquarium filter arrangement with control valve

A method of controlling flow;

• the method comprising:
• (a) providing a housing assembly defining an interior volume;
• a filter cartridge within the interior volume;
• a pump assembly including a pump having an inlet and an outlet;
• a transfer tube assembly having an inlet and an outlet;
• the transfer tube assembly inlet being operably connected to the pump outlet, and the transfer tube outlet being in fluid communication with the interior volume;
• the transfer tube assembly including a tube structure;
• and
• (b) controlling flow through the transfer tube assembly by rotating a valve body between a closed position and an open position in 90 degrees or less of rotation using a valve body rotatably disposed within the tube structure;
• wherein a valve operator is connected to the valve body;
• and
• (c) the step of rotating the valve body includes rotating the valve operator between first and second stop surfaces on the transfer tube assembly.

A filter arrangement for an aquarium, the filter arrangement comprising:

• (a) a housing assembly defining an interior volume;
• (b) a filter cartridge within the interior volume;
• (c) a pump assembly including a pump having an inlet and an outlet;
• (d) a transfer tube assembly having an inlet and an outlet;
• the transfer tube assembly inlet being operably connected to the pump outlet, and the transfer tube outlet being in fluid communication with the interior volume;
• (i) the transfer tube assembly including a tube structure;
• (ii) the tube structure comprising a first tube half and a second tube half mated to the first tube half, wherein the first and second tube halves are bonded to each other;
• (e) a valve assembly for controlling flow through the transfer tube assembly;
• the valve assembly having a valve body;
• (i) the valve body being rotatably disposed within the tube structure;
• and
• (ii) the valve body being rotatable between a closed position and an open position in 90 degrees or less of rotation.
