I DIY'd a solution, didn't see this on here so I thought I would share! I saw a couple ebay/etsy posts selling 3d printed pump holders for upwards of $20...which I thought was dumb.
This is a super simple, cheap, and effective way to keep the pump from moving around the ATO reservoir. airline tubing + strip of hot glue + airline tubing suction cup == stable, non moving pump! suction cup can be found at petco for like $1.50 for 2, or online on ebay- 10 for $5.
