Weir issues

Hello,

The 2nd hand tank I bought has a weir that sticks out inside the tank and I have sometimes found fish swimming in my sump. I stuffed pot scrubbies in there, which worked but looked junky and sometimes slowed down the flow in the overflows if they got into the wrong position. I've replaced them with Poly-Fil, however I had to do some adjusting when that started to get sucked down.

Any ideas on a better option for covering the weir so that the water flows freely but without fish?
