I got it!!! I tried to put it together with common sense, which didnt work out well. I just poured the bio-stuff on the media. Man did i feel stupid when i decided to read the direction's! I made it right, adn now it is working well! A very Nice current. My fish decided they were goign to make up a game called, who can swim against the current! They will literally line up, dart in front of the filter output, and then try to make it as far as they can to the spray bar! They love it, and it has cleaned my tank up nicely! I decided to add the carbon, becasue the one sick fish( that i know of) died, and i scouped it out, and i am too lazy to mess witht he filter again. How long should i leave the other fitler on, before the new filter can catch up on the bio-load?
