I use an Eheim professional 2 2026 which is rated by eheim for a 92 gal, I had 2 of them running it but moved one of them over to another 125 gal, which is housing a pair of large Umbees, Polypterus Endli, Niger Cat and Softshell Turtle. Obviously more needed there and the water params haven't changed on the Aimara tank. I also use two large powerheads towards to ground which help push up any settling of waste into the filter. 40% water changes every two weeks and everything seems to be in check. I only feed once a week, sometimes less so not much waste.
