I run a fluval FX5, Fluval 305, and the sump. The sump pushes 900GPH over the trickle filters/drip tray. I do not have filters in the Fluvals just media. The filters in the sump are just above the brown trim on the sump.....That's all that I use. ...
Excellent Question... He was in a 25Gallon for a year with the cory cat, angel, and rubber pleco. All he did was hang in the bushes/not swimming at all. We got a new couch that was huge (little tank in the way) so I merged the 25 into the 220 and stored the old 25tank in the basement. Once in the 220 he doesn't stop moving. Looks like a real shark on a feeding frenzy when I feed them. I have a 900Gallon pool but I haven't decided when he gets bigger if I'm going to keep him and set up the pool/pond in the basement or take him back to the LFS. I know the 220 will be to small for him once he gets bigger. I love the video on youtube of the 1000G pond with 2 foot and 2 1/2 foot Id sharks in it...
