that is actually fairly common! You'd think they'd learn after the first time too, but nooo!
Make sure your intake for your drains are covered with screen of sponge as that turbo can reak havoc and flood your system. the clown probably wouldn't like the ride either!
Yep, the overflow, my powerheads recently started falling off so I think that might have spooked them into jumping over. My little clown (her parter did that before I got the magnetic power head holders see my post in hardware).
When I didn't see her swimming with her buddy lol. Of couse you think "did my clown die?" Luckily it didn't, and I got the idea to look in the overflows and I saw a reflection of orange and white wiggling around back there and had to take the canopy off and net him out lol. Then about 3 days later the other one did it! My powerheads kept falling off before I got the magnetic holders and I think that had something to do with it. Seeing they sleep right next to the powerheads...
