Hi all, i'm interested in upgrading my force-fed single 55 gallon barrel up flow design (with lava rock) to a ground level gravity fed (multiple chamber) system. ihave a 13 ton system (17feet x 17feet x 3.5feet deep) and would very much appreciate some technical advice on construction and volume needed.i presently have 9 koi in a large pond with a small filter system. i don't want to increase the fish load till i can improve the filtration.
any design features and capacity specs would be helful.
