oh poo. I just few out some old screans a few months ago...Before the animal farm here and my plans at making a Betta Farm. Time to hunt for some old screans or sacrafice one...
Nice going on the tank, btw. I love your contraption for the flow. For my axolotl tank i just put some fake hanging plants in the outflow. Its attractive, the shrimp love to forage on it and it keeps the water pretty still, especially on the lowest setting.
You gave me ideas for an outflow contraption for my covered newt tank....Keep up the good work.
