im trying to make a separator for my 55g. no its not a full tank like you might think, but just the top inch or so. i think im going to use a spare plastic piece thingy from my broken glass top. i just need a way to temporarily attach this to the center brace of my tank. im just trying to coral all my frogbit on my right half of my tank. maybe theres something better i can use, if so give me some ideas lol....

thanks all
