okay this video right here is me installing my Lees 125 gallon under gravel filter. I ordered it off eBay. It says it can fit a 125 and the 150 I think. I had to turn the bottom plank sideways in order for it to fit snugly along the length of the tank. I think 60 pounds of gravel should be the minimum amount of gravel you should use of this filter in a 125 gallon tank. The only reason I'm really putting this in the tank is because I know the koi will sift through the gravel with it there. in hindsight you cannot have tilapia in a tank where you plan on using the under gravel filter because the male tilapia will constantly uncover the gravel. either way this was how you put it. Hopefully give you some good tips and pointers.

Thanks for watching,
