Hi good morning!
I bought a return pump dual nozzle and it’s too big for my tank. I have a 25g WB penninsula. And the one I bought has a 3/4 inch diameter. I hope I’m measuring right! The diameter is smaller on the current one being used shown in picture. Can someone guide me on how I can modify this??
