I have read in the other forum that the output on that filter is half of what its rated for - 160gph (rated 320gph). but then again the poster found his Rena XP1 to have the actual output of 132gph as opposed to 250gph as claimed on the box. both tests were run using the identical method. I am keeping my fingers crossed here.
I have the small powerhead in there now to help my HOB with water circulation and it does a decent job considering its rated at 80gph. so even with 160gph on the jebo I should be OK when using the spraybar.
I will run it the way I had in mind and see what happens especially since there are realy no cons to it. I will direct the spray bar holes down and have the current hit the bottom (not sure if it will actualy be enough to reach the substrate with adequate force) to kick up as much as possible.
I hope it works as I want all the equipment hidden either by tank frame or my background.
anybody know what the white crystals may be? gmh mentioned that it may be zeolite, which I guess is used to remove ammonia. my ammonia readings are at 0 so is there a need for it?
As I mentioned before I would rather use that tray for extra bio media.
