I have a tank that I acquired fairly recently. 96x30x30. Still dialing my maintenance schedule and w/c routine. Previous owner has 2x 40 gallon wet dry filters joined with one 1.5 inch pipe. Also running an Fx6. Wet dry filters contain filter pads and bioballs. anything I can do to make this setup as efficient as possible. Stock includes 5 Bichirs, 2 15-20" Giant Gourami, 5 large Tinfoil barbs and 5 Silver Dollars. I'm still learning with this big tank, sumps etc. Want to keep fish healthy and happy.
