No idea how to... And it's only for a300l tank with 1fh....Heck make a sump man it is way cheaper and can hold the same amount or even more media...
What do you mean submerged sump?i have a pump that will run about 4000lph... Tanks easy to get hold of...That's a bummer. You could build a nice submerged sump for about 75 dollars
The 2080 has a flow pipe that takes the water from the prefilter to the bottom of the canister... And yeah they are $1299 with free shipping here
From the prefilter, the outlet from the prefilter goes down a pipe in the side of the 2080...(right hand front of I remember correctly)If you take out the baskets, how will the water flow to the bottom of the filter?
