This tank is 96x44x30. Filtration is a 125 gallon sump with 4 filter socks, and 12 liters of pond matrix in laundry bags. I have 2 Laguna Max-Flo 2400's. And a power head in the sump keeping the water in the sump moving around a lot.
Never cleaned the sump. I drip 40 Gallons per day so I don't do water changes either. Just change filter socks every 3 weeks and vacuum the display tank bottom. Real simple, real easy.
