i did the most stupidest things today. For the first time after about 6 months, i decided to go ahead and do maintainance on my newly aquired fx5. I was pretty happy on how easy it is to clean, i thought it would look really bad inside, but it looks pretty clean for sho !!! only thing i feed with this tank is mk prawn and hikari floating stiks.
to make long story short, as i go ahead and put everything back together, i forgot to put the intake and outake hose together. as soon as i was under the 125g and pluged it in, the water hit me straight in my face, and then i hit my head on the top of the aquarium as i reacted on the situation. i hit my head so hard that i have a minor gush in my head and feel sum bleeding on top !

i cursed the fx5 up while puddle of water was all over the floor as blood gushed from the top of my head !!!
what a effin bummmer !

what can i say, fx5 is a beast, but it bites you in the butt if you dont be careful
anyone else with this kind of experience with the fx5

I think this coudl've happen to any filters and not just FX5. I remember when I did my first Eheim filter maintaince and I spray myself all wet like I'm in a wet tshirt contest drench in beer.
