I thought I remembered reading a post about this, but I couldn't find anything.
I cleaned my fluval 304 today and put it back under the aquarium. I didn't bother making sure it wasn't leaking at that time. I left for a few hours and when I came home, I lost about 4 gallons from my 75 gal
tank. Apparently, the water was leaking from under the one handle out of a small hole. There are four of these holes on the canister. One on each corner of the indentations where the handles are. I have owned this particular filter for nearly a year now and haven't had any problems and I'm pretty sure that I had everything assembled correctly. Any thoughts or experiences that might shed some light on this?
