tinkerbell 1 Posted July 5, 2007 (edited) before i start, i appologise for the modified pic ok, so heres an easy way to create an air stream in your tank.... As you can see, drilling a hole in the top of the filter head and pushing a piece of air line through (which needs to reach above water level for air to get in) will create a simple way to oxygenate your tank jsut as a warning, it is probably better to detatch the head of the filter from the body before drilling a hole, as you can see where you are drilling too.

Guest avalon Posted July 14, 2007 This also works if you drill the hole in the filter output tube and attach tubing. Its called a venturi... 0 Quote Share this post Link to post Share on other sites
Lady_Dodecagon 5 Posted July 18, 2007 How did you seal off the areas around the tubing, Tinks? 0 Quote Share this post Link to post Share on other sites
nalkari2001 2 Posted June 15, 2012 You will be better to drill the hole in the pump outlet and attache the airline there. The probelm with injecting the air directly into the pump is if the air can destroy the impellor. Paul 0 Quote Share this post Link to post Share on other sites
