I went to Lowe's and bought a 1/2 to 3/4 adapter. I unscrewed my power head and screwed the adapter on. Then I attached the Python T-Valve and attached my python hose to the T-Valve. I have a gravel vacuum with a 25 foot hose that I run to my floor drain in the basement or out the window (or to a toilet if necessary). Then once I get the temp right I add some dechlorinator to the water and close the T-Valve so the water goes down the tube and into the tank. Took me all of 30 minutes to do massive water changes on my 110 and 75 gallon tanks.
